All right, I will bite, and try to tie it all back in to the point of the thread.
Genuine Communism and Capitalism only exists on paper. They are both impossible to implement in the real world without an essential Socialism structure to base their systems on.
For Communism, the common ownership, State control, and semi functionality in the deeply flawed Communist structure requires a Socialist system. For Capitalism, All of the roads, police, military, schools, and other essential components needed for trade to occur are Socialist structures. You could never have a Capitalist, Communist, or any other economic system that would ever function without a Socialist backbone.
We are all just different shades of Socialists.
