MILTON FRIEDMAN: The 4 Ways to Spend Money

"When you spend your own money on yourself, you're very careful of what you spend it on; when you spend your own money on somebody else, you're very careful that you don't spend too much.

When you're spending the government's money on yourself, you're very careful that you get good things for your money.

When you spend somebody else's money on somebody else, you're a distributor of welfare funds, and you're not going to be anything like as careful in spending somebody else's money on somebody else."
