Absolutely! Marxism has worked perfectly all over the world, particularly in the Soviet Union, in Cuba, and especially, in Communist China.
By the way, I would bet that, at this conference, the following was overheard:
"In what order will the delegates speak?"
"Well, Hu's on first."
Marxism works, if you change the defination of marxism to capitalism and belief in command and control economy to free market.
I don't think Hu believes in what he is saying, but is saying it for an alterior motive.
