Sure, I occasionally play the lottery. For a few bucks, you get some excitement. I don't really expect to win.
Someone has called the lottery a stupidity tax. "The more stupid you are, the more you pay." I like that.
There was a very good article on lotteries in Consumers' Research, March, 1996, by James Walsh, entitled "Why Do People Play The Lottery?" Here is a sidebar from that article:
Lotteries and Other Forms of GamblingThe odds in a lottery are worse than other forms of gambling. But those other forms are also slanted toward the people running the games.
Casinos have something called the vig (short for vigorish), meaning the advantage the house enjoys on so-called "even money" and "true odds" bets, on which you're paid, respectively, what you've bet or an amount proportional to your risk.
In horse racing, you bet against everyone else at the track, and typically, the house takes 17% of all money bet. With breakage (the house rounds every payoff down to the nearest dime), add another 2%. That's 19% you have to overcome before breaking even.
These little numbers are the percentages of defeat built into every casino game, or horse race you bet on. In the long run, you will receive back the following number of cents for every dollar gambled on the game listed.
