In the October 2010 edition of Monthly Review, John Bellamy Foster wrote that John Maynard Keynes demonstrated that ”the economy did not automatically [emphasis added—SW] equilibrate at full employment.” (“Notes from the Editors”)
Here Foster does not in any way distinguish his own views from those of Keynes. He seems to assume that Marx as well held the view that while capitalism does not automatically equilibrate at full employment it can be made to do so if the government and the monetary authorities follow policies designed to achieve full employment. This was indeed Keynes’s opinion. But did Marx agree? Is it really possible to achieve full employment under the capitalist system?
