A lottery is a game in which numbers are drawn at random and prize money is distributed to those who match them. While lottery is considered a type of gambling, it differs from other forms of gambling in that payment of some sort (money, goods or services) is required to participate.
For state governments, the primary argument for adopting lotteries has been that they provide a source of “painless” revenue—that is, gamblers voluntarily spend their money on something beneficial to the community, while politicians use the money to avoid raising taxes. However, studies suggest that the popularity of lotteries does not seem to be related to a state’s actual financial condition.
The history of lotteries as public games is a rocky one, despite their widespread adoption in the United States. They owe their origins to ancient practices, including the Old Testament’s instructions for Moses to conduct a census and divide land by lot, as well as Roman emperors’ use of lotteries to give away property and slaves.
Today, state lotteries are a classic example of public policy made piecemeal and incrementally with little or no overall direction. The establishment of a lottery is typically followed by the appointment of officials to run it, with each subsequent decision based on pressure for additional revenues and a lack of consideration for social issues (such as the impact on poor communities and problem gamblers). As such, they operate at cross-purposes with the general welfare.
