--- Ascribed to Jean Jacques Rousseau passim, but may be a paraphrase from Alain de Botton, Status Anxiety (p. 43):
“There are two ways to make a man richer, reasoned Rousseau: give him more money or curb his desires. Modern societies have done the former spectacularly well, but by continuously whetting appetites they have at the same time managed to negate a share of their success”
