Don't know nuthin' `bout no invisible hand.
But the western system of free enterprise works far better than anything else anybody's ever come up with. Don't argue with even a qualified success, unless you've got a better idea. Which you haven't got.
(By the way, the difference between criticism and whining is whether or not you've got a better idea.)
Now theories as just how and why it works... that's a whole `nuther thing. I never did find the notion of enlightened self interest very plausible. But never mind. The point is, it works somehow.
