Well, it really depends on what you mean by Marxism. Karl Marx wrote about 2 dozen books - even on Capitalism. And you're right. Capitalism is turning into Totalitariansim. Fascism is winning fast. Terrible. There's a helluve lot been written about it right now.

Surprisingly, what he had to say about capitalism has been surprisingly prescient.

My late father gave a lecture to the Royal Air Force in 1944 and he said that in a 100 years, the battle would be between Capitalism and Socialism. Isn't that interesting (he had degrees in law, engineering and journalism) and was a very successful businessman.
