"Competition is the law of the jungle, but cooperation is the law of civilization"
- Peter Kropotkin (1842-1921)

UPDATE:
Thanks to some responders, found out that this “quote” is not an actual quote of Kroptkin. He actually thought the “jungle” showed cooperation as well.

@rberger very similar to how I describe capitalism.

Capitalism is a wild stallion. Strong, Fast, and highly unlikely to plow your fields regularly.

reins and tackle are the gov't regulation needed to harness that power for society.

Too tight or too lose and you won't get much work done either. Finding the balance is the tricky part
