A lottery is a form of gambling in which people cast lots to determine their fate or to win money. It has a long history (it is mentioned several times in the Bible), and states adopted lotteries to raise funds for various purposes, including public works. Many lottery proceeds are earmarked for education and other public uses. But lotteries are run as businesses and, like any business, their primary concern is maximizing revenues. That puts them at cross-purposes with the larger public interest.
State-sponsored lotteries typically establish a state-controlled monopoly for themselves; begin operations with a modest number of relatively simple games; and, driven by the need to generate substantial revenues quickly, progressively expand their offerings. The result is that the original policy decisions governing a lottery are soon overwhelmed by its continuing evolution. Few, if any, states have an integrated “lottery policy.”
While the entertainment value of winning the lottery might outweigh the disutility of losing, for most individuals, playing a lottery is a rational decision only if it has positive social consequences. Lotteries have the potential to create positive impacts in a variety of ways, but they also can contribute to problems such as poverty, problem gambling, and a general culture of impulsive spending and irresponsible risk-taking.
