The casting of lots to determine fates has a long history in human civilization, and in modern times it is used to determine such things as military conscription, commercial promotions, and jury selection. But it is also used to award prizes of money and goods. These are called the “gambling” type of lottery, and they are regulated by laws designed to ensure that the prize money is not diverted from its intended purpose. The state lottery is one of the largest sources of gambling in the United States and is operated by the states, often in conjunction with federally regulated industries such as casinos and horse racing. In an era of shrinking government budgets and increasing demands on social services, it is tempting for politicians to promote the lottery as an easy, painless source of revenue.

But the reality is that state governments become dependent on lottery revenues, and it is difficult to maintain a balance between public needs and the desire to maximize profits. Moreover, the development of lotteries is often a case of public policy being made piecemeal and incrementally, with little or no general overview. This is particularly true of the evolution of state lotteries, where authority and pressures are fragmented between legislative and executive branches and further divided within each, making it hard for lottery officials to take the broader picture into account.

For the individual gambler, the decision to buy a ticket is generally a rational one. If the entertainment value and other non-monetary benefits are high enough to outweigh the disutility of a monetary loss, then purchasing a ticket is a good deal for that particular person. But it is important to understand that for many of the people who play the lottery, the entertainment value is just a part of the attraction. They buy tickets because they feel a need for some sort of hope, even though they know the odds are against them.

This is why critics charge that lottery advertising is misleading, with its reliance on glitzy images and a message that plays up the excitement of winning. They also note that the amount of money won is often paid in installments over several years, with inflation and taxes dramatically eroding the current value. Moreover, they point to studies that show that the vast majority of lottery proceeds are directed toward the education sector, and they suggest that this is a clear sign that lotteries serve as a substitute for other, more necessary forms of taxation. In short, the lottery has become a classic example of an industry that runs at cross-purposes with the goals of a democratic society.
