Why Keynes predicted a 15 hour workweek, but Marx did not
One final question raised by John Milios’ paper on crisis theory remains to be addressed.
I have shown that Keynes’ explanation of the Great Depression was identical to that underlying Marx’s prediction that commodity production would collapse, namely the constant reduction of the socially necessary labor time required for production of commodities.
I have also shown that the Great Depression took the form predicted by Marx: a collapse of production on the basis of exchange value. If, as Marx’s theory asserts, exchange value must take the form of commodity money, we should expect the collapse of production on the basis of exchange value to express itself as a crisis of commodity money. The minutes of the Federal Reserve from the outbreak of the Great Depression does indeed indicate that commodity money stopped circulating in the “economy” after 1929.
Keynes failed prediction
Moreover, Keynes initially argued this crisis made necessary both the reduction of hours of labor as well as existing “social customs and economic practices, affecting the distribution of wealth and of economic rewards and penalties”. In other words, Keynes thought the Great Depression established the immanent economic necessity for an end to a society founded on wage slavery. If the critical question debated by the classical Marxists was whether or not Marx had established the immanent economic necessity for socialism, Keynes appears to suggest he did — although he never mentions Marx in his essay.
