Communism
Communism is a form of governmant based on socialist principles. Karl Marx and his associate created the economic system of socialism in which wealth would be redistributed. It was Lenin and Stalin who adapted socialism into the goverment. The motto, more or less, of Communism is "Each gives according to his talents and recieves according to his needs." Until now there has not been a truly communist society, partly because the founders have been power-hungry and in part because humanity has, on the whole, not yet reached a socially acceptable level. 
Communism is the ideal social existance. Once achieved, humanity will be fre from the tyranny of currency and work in order to ensure growth, prosperity and future survival.
