The lottery is a competition based on chance in which tickets bearing numbers are sold and winners selected by lot. It is often used as a form of raising money for the state or a charity. The prizes can be cash or goods. In the United States, lotteries are regulated at the federal and state levels. They can be privately or publicly run, with proceeds benefiting a wide range of public purposes.

In the seventeenth and eighteenth centuries, a lottery was an important part of financing the American colonies, despite Protestant prohibitions on gambling and dice play. It helped fund the settlement of Boston, and it spread to other American cities and towns – including New York – even though New Yorkers were not permitted to own dice or play cards.

Initially, lotteries were promoted as painless forms of taxation. Since most people gamble anyway, the argument went, governments might as well profit from it. The argument had its limits, Cohen writes, but it provided moral cover for people who approved of the lottery for other reasons. For example, many white voters supported legalization because they thought that state-run gambling would primarily attract black number players who, as a group, tended to spend more on tickets and thus foot the bill for services that those same white voters didn’t want to pay for in the first place, such as better schools in urban areas.

But it became increasingly clear that the supposedly harmless lottery was really a tool for extracting wealth from working families. Its rise coincided with a steep decline in financial security for most Americans, as income gaps widened, pensions and job security eroded, health-care costs climbed, and the long-standing national promise that hard work and education would enable children to live better lives than their parents did ceased to be true.

A modern lottery consists of three primary elements: a pool of money from which all bettors are selected; some means of recording the identities and amounts staked by each bettor; and a random selection process to determine the winners. The pool is normally a percentage of ticket sales, with additional expenses, such as marketing and promotion, deducted from it. The remaining money is awarded to the winners.

People choose their winning lottery numbers in all sorts of ways: arcane, mystical, random, thoughtful or thoughtless, numerological, birthday, favourite number, pattern based. Regardless of how they pick their numbers, however, the odds are stacked against them. Only about one in four numbers will be selected in a drawing, and the average prize is relatively low.

Lottery administrators are aware of these realities, and have moved away from trying to sell the lottery as a statewide silver bullet. Instead, they try to convince people that the lottery will fill a single line item in their state’s budget – invariably education, but sometimes elder care or parks or aid for veterans. This approach makes it easier for advocates to justify the lottery as a good thing, and gives states more flexibility when they are deciding whether to adopt it.
