Except Marx was wrong for most of the time after he predicted this as there was a steady rise in wages during most of the 20th century. Further Marx predicted that the first nations to fall to communism would be the most capitalist ones, but in fact the opposite occurred and the least capitalist countries fell to communism, meanwhile the capitalist countries have not. That's just one example there are plenty of other others that can be provided, from how is theory of dialectical materialism was wrong on all counts when it came to any scientific power, to history. In fact the most impressive part of Marx is how truly wrong he managed to be without actually being original as the majority of his work is derivative from Hiegel.
