For just a couple bucks, you might
win money to last your lifetime. Plus we have seductive mottos such as “Someone’s going to lotto”, so why not?
Recent jackpots have also staggered near very high levels (the record $1.6
billion dollars in January 2016, and also a few >$300 million dollars since then including now), and this has
caused many otherwise rational people to tune in to the mania and try their
hand at this gambit. We also see in the recent data that many more people
are turning towards the Lottery for their financial solutions, since the global
financial crisis. The mere fact that people worldwide would be more drawn to “play”, when the jackpot
exceeds many hundreds of millions,
versus when it is “only” in the low
millions, provides a frenzy of opportunity to study the exciting probability
concepts within the Lottery. The conclusions inevitably are still not vague,
especially when you are not emotionally
and financially invested in what amounts to an absurd, money-gouging scheme.
One of the best counsels we have from this article is that you would be
best to scrape up enough money each week to play the Lottery, but then instead boomerang those funds back
into your savings account and simply keep on working through retirement age.
There is simply no expedited-track to success, particularly with the
Lottery.
One should remember that the only objective
for the Lottery, anywhere in the world, is not
to make you rich. Contrary to their
advertisements, the objective is not to show you a good time nor satisfy your dreams. Wasting your money is never a good time. The lottery’s only objective is to maximize the funds you pay for educational
activities. The lottery does this by taking all of the proceeds from whoever chooses to "play", then first
diverting nearly 45% of it towards educational benefits, and also towards store
commissions and advertisements designed to trick you into spending more into
the system. Say you played 292 million times with hypothetically a $1
ticket, and then won exactly one time.
In this case your reward would not
be anywhere close to $292m. The
funnel would start at a gross level of just 55% of $292m (or a loss of
$131m on your ticket purchases since 45% was skimmed straight away to the
government). And then your net amount
would still be less than this 55% gross payout, since this reward is again taxed as
income. There is nothing sexy about this arrangement; it extorts a non-tax
deductible dollar from you and many others, who can least afford it. And
each time putting offering 55 cents into a community savings jar, until one day
that amassed jar is given to basically just one person at random (but not
before the government comes back to tax that jar as “income”). The whole
scheme is an educational tax for those who instead could use a free education
in probability theory (that’s where this blog comes in!)
We approach this article by focusing
on several pertinent facets of the
Lottery, holding of interest something for everyone:
- who is playing and the dispersion in government profits
- the shifting probability of winning
- rebuttal to the Lottery’s official position
- the trends and strategies in lottery wins
- discussing number-picking strategies
- final irony
Please read any or all of these six self-contained sections, as they are segmented below.
Who
is playing and the dispersion in government profits
The dispersion in annual lottery
revenue per state should be adjusted for the number of adults who are playing
in that state. This then gives a reflection of the per person lottery
play that is recently occurring. Getting
to the number of regular-playing adults involves some probability estimation, since
we are working with a large amount of anonymized data. And the calculation otherwise is similar to
how a company would calculate FTEs from a pool of full-time and part-time
employees, since only some play the Lottery full-time while many more play only rarely.
So we start by having a fairly accurately get to the number of adults eligible to play the Lottery in each state. The Lottery provides crude estimates for the total eligible population who play the Lottery each year (~100 semi-weekly drawings). We can also see through the Pareto principle, which broadly aligns to probability theory (see Dollar Cost Averaging math), that not everyone who plays the Lottery, plays to the same extent (some buy more tickets than others). So we back into a conservative estimate for the ongoing number of tickets purchased by the average regularly playing adult per state. That’s what we are getting to, through the chart below. Of the equivalent number of adults who regularly play in the United States (U.S.), the average level of ticket spending per year is roughly $3k! That’s a lot of savings vanquished, and it’s not even homogenously spread across the U.S. States such as Massachusetts’s adult players command over 3 times this national level of ticket spending.

Now why would that be for
Massachusetts, a great state housing two of the world's foremost universities?
Or is the causality going the other way: because of all of the
Lottery playing in Massachusetts, universities such as Harvard have become
so great? Obviously that doesn’t make
sense.
Maybe something else is going on:
for example there is so much Massachusetts’ play because a lone MIT scientist
is hastily rigging the system with,
well, his or her smarts? And that wouldn’t be the first time during
this millennium (here, here). Anyway, that is not right answer either.
A theory about market efficiency makes
sense to bring up here. Let’s revisit
our earlier discussion concerning how much revenue the government makes
directly from these tickets. Examining the records from the available 44 states
(plus the District of Columbia), we see that:
- 24 states have prize payouts between >60 cents, per dollar played. These 24 are in more populated states.
- 21 states have prize payouts between <60 cents, per dollar played. These 21 are in less populated states.
Perhaps the more populated states
have multiple related factors working in their favor. They have efficiencies in scale and a diverse
tax revenue stream, which allows it to offer more affordable lotteries against
their state budgets. And generally at
the same time, the playing adults in those states can and do “afford” larger
lottery spending in these sometimes wealthier states. In truth they shouldn’t still afford it at
all, but these are simply the patterns that strongly match-up. Last, larger states generally have larger
jackpots in the regional lotteries, which attract more playing for that reason
alone and may cause some higher payout affordability. We will discuss later in this article the
interesting concept that as the purse
money swells in any state for a short period, then the conditional payout
swells to arbitrage it away.
Besides looking at payout by frequency
as we just discussed, we can look at the payout weighted (by total ticket sales)
and we see it is more firmly below 60 cents, per dollar played. It is at
nearly 53 cents per dollar, as shown below.
Though in this chart we show the payout yet another way, by the tickets
played per person and we see smaller
playing relative to the larger population in these high-payout states.
It is also important to note that looking
at unemployment levels in the states or in the counties, has no relationship to
the Lottery revenue. Hence economics
tends not to be the dominant driver
here. And in fact regional Federal Reserve research on a small sample of Canadian lottery winners shows that “dissemination
areas” (i.e., homes) in close proximity to lottery winners tend to overspend their
means in order to “catch up” with the instantaneously augmented lifestyles of
the winning neighbors. And hence are at higher risk of
bankruptcy than they otherwise might have avoided. See a version of the plots used below (the black-color star in this actual map was a lottery winner).
The shifting probability of winning
Imagine the fun of catching a ball
at a professional baseball game. These
rare winners take home a trophy that would seem improbable for you specifically
to do. Even though it seems as is a ball
is being hit into the stands at every game. Now, imagine that only one ball is ever hit over the
fence in any one of the U.S. ballparks, every
few years. The likelihood of catching this one ball is suddenly even
lower than it was before. Yet that
probability now equals the current odds of winning the Lottery! Let’s dig into
the actual probability formulae to see how we get to these odds.
1 in 5C69
A common framework for the original lottery is 69 white
balls, of which you must select the 5 correct, unique balls. The probability of this occurring is a
combinatorics (much discussed here, here, here) problem where we have 69 ways
to select the 1st ball, followed by 68 ways to select the 2nd
ball, etc. Also the sequence of the
balls doesn’t matter for anyone, so that could be “factored out” as: there are
5 ways to order the 1st winning ball, followed by there are 4 ways
to order the 2nd ball, etc.
Here are the odds in this hypothetical, 5-white ball only framework:
1 in 5C69
= 1 in 69!/(69-5)!/5!
= 1 in 69*68*67*66*65/5/4/3/2/1
= 1 in 11.2 million
Let’s pause here. Imagine that in this 5-white ball only lottery that we could target a single 100% payout jackpot of $11.2 million, sourced by on ongoing pool of 11.2 million adult players at $1 a ticket.
Now let’s say, for whatever reason, $11.2 million just doesn’t get people excited to come out and play, and so the Lottery is tasked to engineer an even higher prize. Something too big to fail! Welcome a separate urn of 26 hot-red “powerballs”. If one is to win the whole jackpot now, then the probability of this happening is 1 in 11.2m*26 (since one has to now has to jointly match the one correct powerball). Things are getting wild with this new powerball format, and this is precisely where the Lottery gets its stated odds of 1 in 292 million (11.2m*26 red-balls).
Also since the payout happens 26
times less frequently, the government can financially afford to enhance the
jackpot by a little less than 26
times the original $11.2 million we solved for above (i.e., in the 5-white ball
only example). At 26 times $11.2 million
we get nearly $292 million! This is the essential probability and leverage
that takes a jackpot -originally in the tens of millions- and pumps it up to
hundreds of millions albeit with less
frequent winnings. We’ll then also
work on the “less frequent winnings” part next.
Incidentally in the past few years both Powerball and Mega Millions made an actual re-engineering (a perilous response to ward off randomly slumped sales) similar to what we are describing in this section. For Powerball specifically, the change was to increase the number of white balls from 59 to 69, and reduce the number of red powerballs from 35 to 26. This seems like a near wash, but it's completely skewed since the white balls carry far greater probability impact, as we can see as we go from the original odds of 1 in 175 million, to:
1 in 175m*(69!/64!)/(59!/54!)*(26/35)
= 1 in 292m
So nearly twice as difficult! The Mega Millions change was essentially similar. Returning now to our hypothetical situation, the math is going to get a little
more complicated! Even in this case of having winners select all 5 white balls
(e.g., similar to the 5 white-ball only example above). The reason is that while we consolidated all
the winnings to engineer a behemoth $292 million Powerball jackpot, it came at
the expense of one winner every few months, instead of roughly one winner per drawing. Such momentum loss could be a downer, so the
Lottery put in smaller “grab bags”, such as $1 million sub-prizes to anyone
selecting “only” the 5-white balls but failed in selecting the red-powerball. We would expect that for every Powerball
jackpot winner, there would be 25 main prize losers who would instead win the
smaller prize for selecting the 5-white balls and missing the
red-powerball. To afford these greater number of prizes, we must reduce
the $292 million Powerball jackpot by only 25 times the $1 million intervening
prize amounts (or a reduction to only $267 million from the Powerball grand
prize).
The probability of winning these
smaller $1 million prizes would be 25 of 292 million of course, or 1 in 11.7 million. So this now explains the first 2 prize lines
of this odds table pictured on the official Lottery website: since we just showed above how
we get to the 1:292m and the 1:11.7m probability results.
There is still the original 1:11.2
million chance to win the 5-white balls lottery, it’s just that this lottery
was replaced with the introduction of the powerball. So the odds of winning a 5-white ball prize
is no longer homogenous and there are 2 more competitive powerball prizes
instead each with “slightly worse” odds (though winning either collectively
returns one to the 1:11.2 million). The
“worse” odds again are 1:292m for the bigger prize for also matching the
powerball, and 1:11.7m for the smaller prize without the powerball match.
It is worth noting the 292 million
players also happens to be roughly
the size of the U.S. adult population (which is more like a quarter billion). Perhaps the sizings of the Lottery reflects
something about the sizing of the underlying population, ensuring a decent
optimal play level and robust winning occurrences (optimal for the Lottery
though, not for you!)
Of course the easiest prize to win, with the full spectrum of Powerball sub-prizes shown above, is a match of only the powerball itself. Matching the powerball, without regard to any of the white balls, is of course a 1:26 chance. Which can also be thought of as 11.2 million “red-ball” winners, per 292 million plays.
We can change this probability
framework around and appreciate that the chance of matching all 5-white balls,
again, would be 26 such matches per 292 million plays. And it’s the intersection of one of those 26
5-white ball matches, and the one of those 11.2 million red-powerball matches, that
creates only one exciting 1 in 292 million chance of winning the grand prize: simultaneously matching all 5-white
balls and the one powerball!
Now say we have discussed so far a
world, where there is only three prizes offered:
- one for matching the powerball-only
- one for matching all 5-white balls only (25 in 292 million)
- one grand prize for matching all 5-white balls plus the one powerball (1 in 292 million)
= 1 in >26
In other words, there needs to be
slightly more plays per winning red-powerball only prize, since one of those powerball
matches instead counts only towards the
outcome odds of winning the more exclusive larger jackpot (the one where
the 5-white balls must also match). This
is why the bottom prize line of the odds table pictured above shows that the powerball-only
is 1:>26 odds. Not 1:26.
More importantly, the introduction
of the powerball suddenly to the original lottery allows one to cheaply drive up the frequency of having any
type of winnings, from originally 1 in 11.2 million if we kept the Lottery
at only someone winning all 5-white balls.
The Lottery can then slickly market to you that there is nearly a 1 in
<30 chance of winning “a prize”. Even
if that prize can’t even buy you a movie ticket.
For example, how fun, in our current
real-life lottery, with all the sub-prizes added in, you have a one in 38
chance to win exactly, get ready now… $4 (and that’s before taxes)! Yes, you’ll spend nearly $72 (after taxes) though,
to play those 38 times (and there is a >99% chance you won’t get anything other than one or two of those $4 prizes
after spending $72 on those 38 attempts!)
This is how the government more so that Wall Street, encourages you to
be stupid, poor, and despondent.
With the size of the adult playing population
the government sizes the Lottery through the means described above, so that
they can scintillatingly create main prizes that can be optimally won, a few times a year, to just one winner (when approximately the prize happens to swell to
the size of the adult U.S. population and with lottery gaming appetite this
comes to a Powerball or Mega Million prize of about $300 million, which it was
close when won by a sole winner in March 2016).
Jointly, one also wants to ensure that there is also a healthy supply of
cheap-to-fulfill “goody bags” for all the lower prizes to keep excitement on
hand for the next go-around. The price
to fund the red-ball only prize is just <$11.2 million, relative to a grand
prize of <$292 million that is empirically ~8 times the starting grand prize. Since the $292 million was merely a
theoretical hypothetical based upon a full play size. Also recall that $25 million in this case (25
of the $1 million 2nd prizes) was allotted to winners of the 5-white
balls only matches; this is also funded from the same $292 million topline
jackpot money.
With the introduction of these many smaller, intervening prizes
(either through matching less white balls or the introduction of the red powerball
concept) we see that the overall probability of winning any prize to increases slightly (we see in the Lottery odds table
above that it is 1:25, instead of 1:26 or even 1:<26). Maximizing lottery revenue implies
establishing all of the parameters above optimally, for a given lottery region. Note that even for the national lottery,
there are small customizations such as with California players who enjoy smaller
prizes that are set of variable levels
instead of fixed. This allows those
minority of states more finessed revenue tuning, yet more difficult probability calculations for the consumer to
understand!
While discussing probability, we
should be through and note some “housekeeping” matters, which isn’t always
obvious to people at first. The number lottery players has no bearing
on one’s individual ticket’s chance
of winning. Neither does any information
on what other tickets you may have played then, or at any other time. We’ll discuss lottery strategies in a later
section. Note that we already solved the
probability math above, and the number of lottery tickets sold to anyone was
not part of our formula. Hence as a
matter of math, it doesn’t matter. What we have always discussed here in this
article is that the odds of a single
ticket would have to win a specific prize.
Now we carve out South America and state that if you picked a location in South America, then you have won a prize. This probability of choosing this location reflects the probability of guessing the red powerball, or 1:26.
Another way to reinforce what these probabilities mean,
let’s think about the 197 million miles2 of earth and that humans
are hypothetically homogenously spread all across the globe. Randomly pick a spot that you want (e.g., the
Eiffel Tower, the Taj Mahal, the location of the downed MH370 plane, the end of
the Great Wall of China, the North Pole).
Please imagine one small
location on the globe, before continuing.
Now we carve out South America and state that if you picked a location in South America, then you have won a prize. This probability of choosing this location reflects the probability of guessing the red powerball, or 1:26.
Further, what about the probability
of guessing all 5 white-balls? This is
now an area of just 18 miles2.
Or of all places in the world, guessing Rio de Janeiro’s Galeão
International Airport. Is that what you
imagined, or would eventually imagine?
Didn’t think so, yet this reflects a 1:11.2 million probability outcome.
Still think you’ll be able to guess
the winning region picked for the big jackpot?
Think there is a “pattern” to this? You’d have to have guessed Estádio Jornalista
Mário Filho, the soccer stadium of Rio that will host part of the 2016 Olympics. Guessing
the main prize correctly means predicting a random place on earth, a place the
size of a soccer field (less than 1 mile2)! And this is a 1:292 million outcome that one
would have guessed this correctly!
Now we shift gears from this base of
probability work, and we can expand our framework in advanced ways to take into
account multiple players competing for similar prizes over time. And the probability work will continue to
become more fascinating! In the chart
below we show the probability of someone
winning the 1:292 million grand jackpot based on the number of other players also buying a different tickets,
repeatedly over a certain number of drawings.
We can get to 100% probability
multiple ways. The first of course is
that we have 292 million players (continue to see the bright orange color
curve). Another way of course is that we
have 29 million people buying tickets over and over, over 10 drawings, all with
no replacement (see the dark red color curve).
These are dispiriting probabilities for
what it takes to win the advertised Grand Prize: after shelling out hundreds of millions on tickets
(collectively by tens of millions of people over a couple handful of drawings),
only improves one’s chance from near 0%, to just over 50%.
But the issue in the real world is
that the tickets bought by the public are not always unique. Just like in our pick-a-spot-on-the-globe
guessing game we did earlier, we often
have overlaps among lottery numbers that have overlapping “special” meanings
for people. If we instead consider the
probability associated with randomly
selected (i.e., with replacement) ticket numbers, then the probability
associated with someone winning the grand jackpot stays more muted, and many more tickets played over even more drawings need to occur in
order to have the same number of unique numbers. And therefore to achieve the same >50%
probability. We can infer -from the
chart below- that during January 2016’s record jackpot, hundreds of millions (of
dollars) of tickets were being bought in each of those peak drawings. And then created the well-publicized >80% probability for someone to win
any particular drawing at that time.
To
reinforce the concepts between the two charts above, notice that in the chart
immediately above that the 1-drawing bright-orange curve and the others are
running lower than the same curve on the chart above that? 292 million single plays would be 100% probability
of someone winning in the former chart, where as it only leads to 63% probability
in the latter chart.
Rebuttal
to the Lottery’s official position
For their
part, the Lottery’s quants and lawyers have issued new entertaining guidance to help policy makers and
potential players understand their game.
They state
for example that one is more likely to win a jackpot than to be struck by
lightening, except it errs in noticing that more Americans don’t go out
venturing in a thunderstorm versus play the lottery, so looking at the
probabilities without properly adjusting for those who try, is an error.
They also
state something laughable: “That’s
when you take a certain zip code, look at total lottery sales within that area,
and then assume that everyone in it has the same income and refuses to play the
lottery anywhere else. … It’s like saying that gasoline purchases are made
mostly by poor people, because there are few gas stations in wealthy
neighborhoods.” Is this a
suggestion that wealthy individuals are waiting in line in a poor
neighborhood’s 7-Eleven to buy lottery tickets?
Followed
by something as kooky as it is dangerous: “In our stressful world, the ability to dream is well worth the price
of a lottery ticket.” Why would lottery players be stressed, if the Lottery is actually advertising to the wealthy? Oh yes, the ads are only designed to attract the less wealthy.
Their
guidance last year had other points, but neither had a comment section for
citizens to voice their opinion. They
had stated for example, “The rich also
invest and gamble in stock and commodity markets -- also activities the poor
cannot afford.” But the Lottery
is not an investment! We’ll see
later that those investing their retirement are almost assuredly going to do
better than a scheme that skims 45% off the top and taxes any winnings.
They also
haughtily ranted off incoherently in other topics about not having to complete
a Form 1040 (implicitly acknowledging that you aren’t going to win), to the
poor having the right to entertain themselves straight into deeper poverty: “The purchase of a lottery ticket is
completely voluntary - and a lot more fun than filling out Form 1040. … This
question implies that economically disadvantaged people are somehow less
capable of making a decision on how to spend a dollar than those of greater
means or that they are not entitled to the same opportunities for entertainment
and recreation than the rest of us. The poor are allowed to vote, get married,
and sign contracts.”
Which
brings us all to a situation where someone already poor might lose a lot of
money often, and feel as if they are a problem gambler. The Multi-State Lottery Association provides as a resource this broken site. Now that’s
official entertainment.
This issue was also picked up by comedian John Oliver who found the addiction recovery sites featured pop-ads to gamble! Mr. Oliver also noted "The Lottery is in the business of selling people hope. And they do a great job of that … feels like an ad for a mutual fund. But crucially, the Lottery is not an investment. Because it’s worth mentioning that those Mega dreams are Mega unlikely to happen.”
The
trends and strategies in lottery wins
The actual time gap between the
major lottery wins throughout history reveals a mild inverse relationship
between the size of the jackpot and the time to have a jackpot winner. We highlight the recent January jackpot of
$1.6 billion (available as a $983 million lump sum as shown) which was won 105
days after the sole winner of September’s sizeable
jackpot win of $197 million.
Additionally we notice other trends
in these major jackpot
winnings. The amount of playing has
picked up alongside the jackpot sizes, at a much faster rate, since the global financial crisis (GFC).
Sure the odds are more difficult now versus before, but this only means
the frequency between wins would be wider unless
there was more disproportionately more playing. What we are witnessing is a
consequence of, according to Discovery,
“1/3
of people in the United States think winning the lottery is the only way to
become financially secure in life.”
One of the intriguing probability
ideas also in this lottery business is that a model can be used to determine
the distribution of how often the lottery is won. This is similar to the basic concepts (discussed in depth in our Statistics Topics bestseller that is free on Amazon Prime) of the
Poisson and binomial model, and the more advanced math of convolution which is the
study of frequency and severity and one we even prove here has stumped famous
Nobel Laureates (here,
here, here). The basic result of this model that ties
together all of the revenue and odds parameters we have thusfar discussed about
the lottery is that the typical time needed to win the grand prize is only several drawings (by which point the
jackpot size can balloon to about $75 million to $125 million). 70% of the wins occur within a few lotteries.
So equally, the other 30% shows
lottery wins that take more than several drawings to achieve. And the overall typical time in-between the
larger payouts (>~$300 million) for the overall system is just less than a year (<50 drawings). By making engineering the odds to have higher
jackpots, which we discussed in a previous section, we should have made the winning frequencies less, however as we are
noticing here the greater playing since the GFC is reflected instead in more frequent winnings of somewhat large
prizes!
The idea here is that as jackpots
swell (and buffeted by financial insecurity after the GFC), the wins must be
arbitraged away since the pot sometimes will grow far in excess of the equilibrium
amount of money we previously discussed that needs to be put into the system. So there is an economic imbalance. And enough people will play in order to
guarantee a winner quickly, after the pot zooms over levels in the hundreds of
millions of dollars (e.g., the >$300m jackpots shown above).
Discussing number-picking
strategies
Some strategies abound concerning
being owed a magic number to be generated by the Lottery. This “special number” could be derived from
some divine calling, or a symbolic number such as a birthday or anniversary, or
simply contrarian plays such as avoid popular birthday numbers. Would such strategy have worked in our
previous example of “pick a location on the globe” quiz, earlier in this
article? Of course not, yet when it
comes to the Lottery people tend to believe that mythical, supernatural forces
can help them.
So
it is true that some numbers tend to be more popular across the globe. Again the probability of any such number winning is not impacted, as we
discussed in a previous section. However
more people selecting a popular number –when that number happens to win- will
receive a smaller share of the jackpot prize as it is of course split among
more winner. In the chart below, constructed
from data Professor Tijms showed in the University of Cambridge book “Understanding probability”,
we see that in the British lotteries there are some “patterns” among popular
customer lottery number picks.
Lucky 7 is the most popular (in
other studies there has been a slight
uplift relative to neighboring numbers for all numbers ending in “7” such as
17, 27, 37, 47), and unlucky 13 is unpopular.
Birthday numbers (e.g., 1-30) are more popular then numbers >30. Finally per Benford’s
law of naturally occurring numbers, the
smaller single-digit numbers tend to be quite
popular (e.g., if one finds the number “5” special and can’t select any
numbers in the 50s, then they might instead select “5” as opposed to a 2-digit
number ending in “5”). Notice that the
downward trend in popularity after the first ten or so digits has a high R2
fit?
This is the same concept (though likely with less impact) as being economically
advantageous. Again the odds won’t
change, but one would want to only be
playing the unpopular numbers (e.g., those in the upper third of the number
range) and during large jackpots. Still all of these gambling improvements may
only increase your economic advantage by far
less than the magnitude of the 45% skim that the Lottery takes off the top. Recall that you could play nearly 400 million dollars’ worth of play (and
unless you have multiple grocery stores ensure you get all those different tickets printed up within a
few days) in the current lottery system ($2/ticket) you would still have a 50%
chance of not winning!
200 million tickets at a 1/10 second
a ticket is 20 million seconds (231 days).
You would need to be at 77 stores to print tickets just for you at this speed
around-the-clock and never have any of these stores print a duplicate number
combination of any of the other stores.
Let’s pull back for a minute to make
sure that we are not losing the sight of the forest through the trees. We see from the Lottery revenue data that most
regular adult players will play ~$30
a drawing. At 2 drawings weekly, for 45
adult years, we come to $135k in
after-tax money wasted, over an adult lifetime. So let’s discuss a final irony concerning
this.
A final irony
A final irony
We noted above the typical adult player will waste $135k. This does not imply the median spending of anyone who will have ever played
lottery in their life! An incredible
portion of American adults (~95%) will either never play, or will play such a
small fraction of this level. But there
is a minimal number that will be regulars, who bring in nearly ½ the total
revenue to keep this system afloat, and will be the ones who play nearly $135k in a lifetime. Averaging the level of play among all people who ever play, we could
still get to over $25k in a lifetime.
Both of these statistics are significant, as per the Federal Reserve
(page 12), the median net worth of a
family approaching retirement is $166k (per individual adult it would be nearly
half this).
So imagine that. One could have their nest egg guaranteed to be enlarged by $135k, instead
of religiously trying to score a million-dollar mirage and instead being stuck
poor. And if one were instead save this
money at a conservative 2% rate of return, then they would have by retirement
age $215k just from these lottery savings.
Enough to pay for 4-years of private college tuition, or a small home in
a rural part of the country, or a lifetime annuity of >$500 monthly.
One will also notice in these charts
the same heterogeneity in adult playing levels across the U.S. In Massachusetts and neighboring Rhode Island
-for example- the typical adult who has
ever played lottery, wastes nearly $20/drawing over their lifetime (3 times
the national average). And the payouts
there (shown the first section above) is not always larger for these two states. Also their lifetime spending (savings accruing at a modest 2%annually) for all players in those states, equivalently comes to ~130k. Or >$650k for the serial players. Incredible sums that will work out to several multiples of one’s salary (but for a small percent of Americans), and ironically
more than the 2nd prize of $1 million, after-taxes.
Lottery killjoys never include the entertainment value in their ridicule of playing.
ReplyDeleteOne could quite easily spend 30 dollars on wine a week and what do you get for that? Worst case (after an unprotected drunken frolic) - kids! How much do they cost you over their childhood?
that's a huge leap, from drinking wine (which i agree is a waste), to having a child.
