A lottery is an activity in which you pay a fee to be given the chance of winning a prize, usually money. There are also other kinds of lotteries, such as those for housing units in a subsidized community or kindergarten placements at a reputable public school. Federal law prohibits the mailing of promotions for lotteries or the transportation of lottery tickets across state lines, and state laws define how much you must pay for the chance to win.
The one-in-a-million chance that you will be the winner of a lottery prize can be fun to fantasize about, but it’s also not cheap to play for: Many studies find that low income people make up a disproportionate share of lottery players and that playing lotteries can be a hidden tax on their families. Lottery retailers must collect commissions on ticket sales, and the costs of running and promoting the lottery drain the pool of prizes available to winners.
Lotteries are a classic example of public policy made piecemeal and incrementally, without a clear picture of the overall public welfare. State governments establish a monopoly, hire or create an agency to run the lottery, begin operations with a modest number of relatively simple games, and then — in response to constant pressures for additional revenues — gradually expand their portfolios. The result is a complex mix of gambling activities whose results are often unpredictable. In addition, most state lotteries are run as a business with a primary goal of maximizing revenues. This commercialization of gambling runs at cross-purposes with the state’s mission to promote general welfare.
