I find it unfortunate that the "invisible hand" is somehow seen as a real force of nature. It's a spooky, ideological term that implies some kind of simple generality describing a system that is everything but simple. Additionally it is used as a bad excuse for exploitative, oppressive or otherwise shitty behavior - which is ironic, because that is exactly the thing that is claimed _not_ to happen by definition.

There are real firms in highly competitive markets that have been doing well for decades or even more than a hundred years without putting the profit motive above everything else, but have favored long term stability, cooperation, servicing customers, respecting workers and so on.
