Generally speaking, a lottery is a form of gambling in which numbers are drawn for prizes. The prize money is often split among a large number of participants. Many lotteries also offer a single grand prize of considerable value. A lottery is a popular method of raising funds for a variety of purposes, including education and public works projects. It is also a popular method of distributing government benefits such as tax rebates or subsidized housing.
Historically, lotteries have been seen as a way to expand state services without onerous taxes on middle- and working class citizens. This arrangement became especially attractive in the immediate post-World War II period, when states were expanding their social safety nets and wanted more revenue.
State lotteries have proven to be a useful source of painless revenue, and have resisted attempts to abolish them. This is because people just plain like to gamble, and lotteries dangle the promise of instant riches, even though the odds are very long.
Moreover, lotteries have been very successful in building broad general public support and developing specific constituencies. These include convenience store operators; lottery suppliers (who make heavy contributions to state political campaigns); teachers in states that earmark some lottery revenues for their schools; and state legislators, who quickly become accustomed to a regular stream of lottery income. In addition, the general public is often reassured by the fact that the lottery is “fair” – that it is a matter of chance and does not discriminate against poor or minority players.
