Can Karl Marx Save Capitalism From Itself?

George Magnus thinks we need to note a few of Marx's critiques of capitalism (via nc links):

The spirit of Marx, who is buried in a cemetery close to where I live in north London, has risen from the grave amid the financial crisis and subsequent economic slump. The wily philosopher’s analysis of capitalism had a lot of flaws, but today’s global economy bears some uncanny resemblances to the conditions he foresaw.
Consider, for example, Marx’s prediction of how the inherent conflict between capital and labor would manifest itself. As he wrote in “Das Kapital,” companies’ pursuit of profits and productivity would naturally lead them to need fewer and fewer workers, creating an “industrial reserve army” of the poor and unemployed: “Accumulation of wealth at one pole is, therefore, at the same time accumulation of misery.”
The process he describes is visible throughout the developed world, particularly in the U.S. Companies’ efforts to cut costs and avoid hiring have boosted U.S. corporate profits as a share of total economic output to the highest level in more than six decades, while the unemployment rate stands at 9.1 percent and real wages are stagnant.
U.S. income inequality, meanwhile, is by some measures close to its highest level since the 1920s. Before 2008, the income disparity was obscured by factors such as easy credit, which allowed poor households to enjoy a more affluent lifestyle. Now the problem is coming home to roost.

Note that corporate profits are high even as sales are flat.  Productivity gains equals fewer workers producing the same number or more goods.  In the current political situation, we have zero chance of listening to Marx's critiques of capitalism.  I'm afraid the misguided proponents of uncontained capitalism may allow it to destroy itself.
