According to communist theory, ALL economics is capitalist economics, because an actual system of community economy wasn't created yet, as it requires a communist society, which humans are unable to build because of their inherent nature as individualist resource-hoarders.>Hell, even perfectly working communist societies would still suffer from economic necessities on a country wide scale.
No they wouldn't. A communist society is one that distributes the wealth according to it's citizens needs, thus removing any economics necessities.>No. The true enemy is all living creatures desire to breed. And the inequality of resources a massive population creates.
Which is the over-pinning principle that gives rise to capitalism, yes. Marx acknowledge that fact.
It's only the modern liberals who haven't actually read any of the communist authors, who have been fed the american-dream propaganda of individualism, that juuust by sheer accident happens to serve the interest of giant corporations and nobody else, who actually think that communists a) don't understand that the problem is human nature and b) that communism as it has been called and implemented is in any way comparable to the theoretical economic construct suggested by Marx and Engels.
Sorry for the /pol/ rant. I can't help it when people misrepresent the most accurate economic theory ever proposed.
