Karl Marx was right?

Interesting piece on the BBC about people re-evaluating Marx's theories on Capitalism

As a side-effect of the financial crisis, more and more people are starting to think Karl Marx was right. The great 19th Century German philosopher, economist and revolutionary believed that capitalism was radically unstable.

It had a built-in tendency to produce ever larger booms and busts, and over the longer term it was bound to destroy itself.

Marx welcomed capitalism's self-destruction. He was confident that a popular revolution would occur and bring a communist system into being that would be more productive and far more humane.

Marx was wrong about communism. Where he was prophetically right was in his grasp of the revolution of capitalism. It's not just capitalism's endemic instability that he understood, though in this regard he was far more perceptive than most economists in his day and ours.

More profoundly, Marx understood how capitalism destroys its own social base - the middle-class way of life. The Marxist terminology of bourgeois and proletarian has an archaic ring.
