"Grade school economics teaches that subsidies raise prices. Give a man $2 every time he eats fish, and he’ll quickly develop a taste for it. Do the same everywhere, and prices will soar while workers scramble to become well-paid fishermen and mongers. But a man can only eat so much fish. You can raise his subsidy to $3 or $4, but eventually you’ll end up with gluttony, skewed prices, strained waters, a bloated budget and a work force with skills that match public policy but not private need."
