A lottery is a form of gambling in which people have a chance to win a prize in exchange for a sum of money. State governments sponsor lotteries to raise revenue for a wide variety of purposes. Generally, each lottery ticket costs one dollar, and the amount of money paid out in prizes exceeds the amount of money paid for tickets. Consequently, lotteries produce substantial profits for the states.

During the eighteenth and nineteenth centuries, as America was building its banking and taxation systems, it used lotteries to quickly raise funds for public projects. Lotteries helped build Harvard, Dartmouth, Yale, William and Mary, and many other colleges. In addition, famous American leaders such as thomas jefferson and benjamin franklin sponsored private lotteries to help relieve their crushing debts and buy cannons for the city of Philadelphia.

In virtually every state where a lottery has been introduced, the arguments for and against it have followed remarkably similar patterns. For example, state lotteries are usually promoted as a way to raise “painless” revenue—that is, taxpayers are voluntarily spending their money for a public benefit (such as education) rather than having it taken from them in the form of taxes.

The second main argument against state lotteries is that they are a form of regressive taxation—that is, they hurt poorer citizens more than wealthier ones. This is based on the observation that lottery players, particularly those who play scratch-off games, are drawn heavily from middle-income neighborhoods and far less proportionally from high-income or low-income neighborhoods.
