“When the biologist Daniel Lieberman suggested in a public lecture at Harvard this past February that exercise for everyone should be mandated by law, the audience applauded, the Harvard Gazette reported. A room full of thin affluent people applauding the idea of forcing fatties, many of whom are dark, poor and exhausted, to exercise appalls me. Government mandated exercise is a vicious concept. But I get where Mr. Lieberman is coming from. The cost of too many people getting too fat is too high.”
How would Sunstein and Thaler respond?
