Sorry Uberman-you are mistaken. Capitalism is not based on greed, but rather based on the idea that the fruit of a
man's labor belong to that
man to decide how to use. It simplifies the barter system, by standardizing the trade mechanism into a form of "capital" (hence the term).
With capitalism, if I grow a better crop, I get to keep that crop and trade it for capital, which I can then use to purchase things I need. Rather than have to trade my wheat for chickens I don't need, to trade those for the iron I do need.
Under
socialism or communism, individuals do not own/control the fruit of their labor, but rather the community or the
Government does.
Not a very good thing.
Perversion of anything is
bad...but don't blame the mechanism for the faults of humans.
