Stop wasting your money on lottery tickets. Don't even give me the "but it's fun to imagine what I could do with that money" excuse. There's a reason why economists and mathematicians call lotteries a stupidity tax. Because a rational individual would never play the lottery. In the long run, you are guaranteed to lose money.
Even CNN is reporting on the 500 million+ jackpot for Powerball and it's distressing to think that it got to such a huge amount because a bunch of stupid and poor (the two are not entirely synonymous) people paid for the hope of getting really, really, really, really ridiculously lucky.
Unless the state gaming commission is also terrible at math (there have been instances), lotteries are designed in a way so that every participant has negative expected value. For example, imagine a game in which you flip a fair coin and every time it landed heads, you gained a dollar, but every time it landed tails, you lose two dollars. If you kept playing the game, you would eventually bankrupt yourself.
Lotteries aren't designed to make people rich. They're designed to let morons fund state education programs. It's essentially a transfer payment from poor and stupid people to K12 and college students. The hope of winning it big is just absurd. Serial lottery ticket purchasers would be much better off stashing it in a no-load mutual fund, or even just buying a chocolate bar instead of a ticket. At least a chocolate bar has real, practical utility.
The other argument for buying lottery tickets is that it goes to a good cause (education). If that were the case, just cut a check to the state government.
This is why I'm a libertarian and I believe in small government. Because the government (more specifically, the state governments) is directly manipulating the public into buying tickets with clever phrases like "today could be the day" and other forms of TV, billboard, and radio advertising.
That is the government directly acting against its constituents' best interests. If a company wants to do it, sure. But the government sure as hell shouldn't.
