Lottery is a game in which numbers are drawn at random to determine winners. The winnings can be cash or goods. Often the lottery is run by state governments, although private companies also conduct games for profit.

Lotteries have a long history, and were widely promoted in the postwar period as a way for states to expand social programs without onerous taxes on the middle and working classes. But even in the era of high incomes, state lotteries have proved a regressive source of revenue, because people who make less money play them more often. And advertising, which necessarily focuses on persuading target groups to spend their money on the lottery, can produce problems such as addiction and irresponsible gambling.

Despite this, the vast majority of Americans support state lotteries. The reason seems to be that lotteries are seen as a painless form of taxation, and are especially popular in times of economic stress when the public might be expected to oppose state government spending increases or cuts in services. But studies have shown that the objective fiscal circumstances of a state do not influence whether or when it adopts a lottery.

Lottery advertising tends to promote the idea that winning is easy, and encourages people to “have a go.” This coded message obscures the regressivity of state lotteries, and makes it hard for people to think about how much the lottery really affects the bottom line of those who spend the most on tickets.
