The lottery is a tax on people with bad math.
They've designed the game in such a way as to discourage frequent payouts, in order to drive jackpots higher. They do this because the math-challenged masses actually react to lack of payouts by increasing their ticket purchases. Bizarre. But it works, and generates a lot of money - not for schools and stuff, but for the bloated bureaucracies that administer them and for the millions spent in advertising.
BTW, a tip for the math-challenged: buying 1,000 tickets does not increase your odds by any statistically-significant amount over buying 1 ticket. So if you must participate, buy one ticket. And let the computer pick the numbers for you, there is nothing magical about your childrens' birthdays.
Lest you think I'm a hopelessly grumpy old man, my wife buys lottery tickets every week, so I'm covered. I'm assuming, of course, that she'd share her winnings with me.
