From a link in LabRat's Parasite memes and monkeyspheres, David Wong's Cracked.com piece What is the Monkeysphere?:
(S)ome people in the distant past naively thought they could sit all of the millions of monkeys down and say, "Okay, everybody go pick the bananas, then bring them here, and we'll distribute them with a complex formula determining banana need! Now go gather bananas for the good of society!" For the monkeys it was a confused, comical, tree-humping disaster.
Later, a far more realistic man sat the monkeys down and said, "You want bananas? Each of you go get your own. I'm taking a nap." That man, of course, was German philosopher Hans Capitalism.
As long as everybody gets their own bananas and shares with the few in their Monkeysphere, the system will thrive even though nobody is even trying to make the system thrive. This is perhaps how Ayn Rand would have put it, had she not been such a hateful bitch.
