Communism is structured upon the common ownership of the means of production for all citizens, do you know much about communism?
I know a little, I mean I know about Karl Marx? Is that where it all started? 
Correct! that is when it became popular after his publishing of the communist manifesto.
Cool! What about now? Any communist countries exist?
Of course, most forms of communism is still grounded in marxism, for example the Russian Federation is still largely a communist nation.
Wow! What about Cuba?
Cuba is still also largely a communist nation, the goal is to put the working class in power and in turn establish social ownership for the citizens.
