I hate that people call Capitalism an "economic system," to "economize" means to make more efficient, to avoid waste, and to conserve... it does the opposite. Also, what makes people think that "free markets" means anything other than "every man for himself"...that's an anti-system and proven not to be a good way to run any large population. Basically, Capitalism is a distorted form of Social-Darwinism (not to be confused with Natural Selection, an ACTUAL scientific theory proposed by Charles Darwin). Social-Darwinism, and hence Capitalism, is an incorrectly understood and applied, distortion, of what science tells us about evolution. It hides behind the legitimacy of science (which it does not earn), and also hides behind the mysterious religiosity of "the invisible hand"...a psychological tool that allows them to claim that it is so complex, they need not try to figure it out.
In reality we have the tools and historical records to assess our resource usage, distribution, carefully weigh that against our ethical concerns/values, and address the complexity that comes with an interconnected and interdependent planetary species. I'm tired of this lazy religion we call Capitalism, and it needs to be greatly reformed at the least, and ground-up rethought at best.
