He's been right about the avalanche of bad debt and derivatives problems we've encountered. Of course, the problem is that one can be very right about the problem and equally wrong about the solution. Marx was right when he said the harrowing conditions under which the industrial worker labored were unsustainable, and wrong when he said the solution was armed revolution.
I would reread Marx. You've drawn the wrong inferences. Marx expounded upon a narrow time period during the history of the island of England. The “harrowing” conditions of the industrial worker were a major improvement over the harrowing conditions of the agricultural worker. The conditions of workers just kept getting better and still are.
Marx got it all wrong.
