Lotteries are a form of legal gambling. They are operated by state governments. The proceeds are credited as aiding a specific public good, such as education.
Although many argue that lotteries are unproductive and have harmful effects on low-income families, the fact is that a significant number of Americans play the lottery. Typically, the jackpots are very large, and they generate tremendous publicity. And even though the likelihood of winning is small, the cost of a lottery ticket is nominal.
Lotteries are an important source of revenue for state governments. Most states collect between 20 and 30 percent of gross lottery revenues. These revenues are used for certain programs, reducing appropriations to the general fund.
Some critics have raised concerns about the impact of lotteries on problem gamblers. They say that new games have increased the opportunities for problem gamblers. Other concerns include the use of advertising to persuade target groups to participate in the lottery.
In response to these concerns, the US government has banned the sale of lottery tickets across state lines. Additionally, the federal government invoked the Commerce Clause in 1890 to prevent mail lotteries.
Most state legislatures have enacted laws requiring approval by the public before a lottery is established. However, there are few state legislatures that have developed a coherent gambling policy.
State lotteries are a classic case of piecemeal public policy. They are established with a modest number of simple games, and the number increases as the industry expands.
