Henry Miller said this quote

He is sure to be more happy who has eaten well and slept well and has besides a little money in his jeans. Such men are rare to find for the simple reason that most men are incapable of appreciating the wisdom of such a simple truth. The worker thinks he would be better off if he were running the factory, the owner of the factory thinks the would be better off if he were a financier, and the financier knows he would be better off if he were clean out of the bloody mess and living the simple life.
