Statistics from South Carolina highlight the lottery’s reliance on low earners: people in households earning under $40,000 made up 54 percent of frequent players, while constituting only 28 percent of the state’s population. Meanwhile, a PBS report earlier this year showed that, for America’s very poorest, the lottery is a heavy expenditure: Households that earn at most $13,000 a year spend 9 percent of their money on lottery tickets.
