An alternative future
When people talk about the failure of Capitalism the immediate response is the false equivalency of state Socialism and any useful examination goes out the window. John Maynard Keynes wrote an essay in 1930 in praise of Capitalism because he thought that once people had enough they would enjoy the fruits of their labours in social activities.
Keynes thought that the motivational basis of capitalism was "an intense appeal to the money-making and money-loving instincts of individuals." He thought that with the coming of plenty, this motivational drive would lose its social approbation; that is, that capitalism would abolish itself when its work was done."
