Like many public figures who leave a legacy, either in their writings or their deeds, Karl Marx was sometimes right and sometimes wrong. I concentrate on some of the things about which he was wrong.
He was wrong to predict that history would take us to the inevitable triumph of the proletariat and then stop. History shows no signs of doing either. Marx was also wrong to suggest that this would happen first in the most advanced economies as the final stage of capitalism. In fact such revolutions as came took place in less developed economies such as Russia and China. It has not happened in the advanced economies, and this could be because Marx was wrong about something else.
He predicted that capitalism would drive down wages to survival level before its final denouement. In fact as economies became more advanced, both wages and living standards rose to levels not even dreamt of in Marx's day, and this seems to have lowered the pressure for revolutionary change.
