“There Ain’t No Such Thing as a Free Lunch.” I used to think that originated with Robert Heinlein’s The Moon is a Harsh Mistress. Many others credit Milton Friedman. But read the real story. A San Francisco newspaper is the earliest known source. And Professor Alvin Hansen, preceding Friedman, wrote of TINSTAAFL, which is simply TANSTAAFL with better grammar.
