Capitalism is systematic exploitation. The owner of capital does not invest in order to use the capital himself; he invests to extort the labor of others.
The very act of capital investment is the act of an extortionist.
Capitalism can not be fixed because it is not broken; it works exactly as it is supposed to.
"It is only by the abolition of the state, by the conquest of perfect liberty by the individual, by free agreement, association, and absolute free federation that we can reach Communism - the possession in common of our social inheritance, and the production in common of all riches." ~Peter Kropotkin
"Let us fight to free the world - to do away with national barriers - to do away with greed, with hate and intolerance. Let us fight for a world of reason, a world where science and progress will lead to all men’s happiness. Soldiers! in the name of democracy, let us all unite!" ~Charles Chaplin
"Communism is Anarchy. You can't regulate or reform your way to communism; it can only be achieved by direct action against state, class and capital."
