Lottery is the state-sponsored gambling game that involves picking numbers and chasing dreams of wealth. It’s a big business and a major source of state revenue, but it also has an ugly underbelly that’s worth exploring. This is especially true in the United States, where people from the bottom quintile of the income distribution are far more likely to play and to spend the most money on tickets.

This isn’t just because of some inextricable human impulse to gamble and hope for a better future, although that’s certainly part of it. It’s because lotteries are dangling the promise of instant riches in an age of inequality and limited social mobility. In this era of stagnant wages and increased competition for jobs, many Americans feel they need to supplement their incomes with something that will give them a leg up, and the lottery offers them just that.

The casting of lots to determine fates and distribute material goods has a long history in human society, including several instances in the Bible, but the introduction of lotteries to raise money for public purposes is relatively recent, dating back only a few centuries at most. During the immediate post-World War II period, when many states were expanding their array of services, politicians looked at lotteries as a painless way to raise money without burdening the general populace with onerous tax increases.

When lotteries first emerged, they typically resembled traditional raffles in which people bought tickets for a drawing at some future date, usually weeks or even months out. But innovations in the 1970s changed everything, allowing for new types of games and dramatically increasing revenues. State lotteries have become very much like any other regulated industry, and they are constantly evolving in order to stay competitive.

The biggest problem with this evolution of the state lottery is that it often leaves behind specific constituencies that are highly dependent on the industry. This includes convenience store operators who sell a lot of tickets; lottery suppliers (whose contributions to state political campaigns are regularly reported); teachers, in those states where lottery revenues are earmarked for education; and, of course, the politicians who have grown accustomed to the big revenue stream that lotteries provide.

These constituencies are incentivized by the fact that they can direct some of their lottery proceeds to their preferred cause, which tends to be some sort of government program or project. And these interests are well represented in state legislatures and executive branch offices, which means that the general welfare is only taken into account intermittently if at all.

So, if you decide to play the lottery, it’s important to keep in mind that there is no such thing as a free lunch and that the odds of winning are incredibly low. The best strategy, therefore, is to play the Quick Picks – or, as one Harvard statistics professor puts it, “pick numbers that are not significant dates or personal numbers.” That way, you won’t have to share your jackpot with anyone who happens to be using their birthdays or home addresses.
