Keynes and Hayek - a battle without an ending

Why do smart people still choose Keynes over Hayek?

Looking back over the last few years you have to ask how intelligent people, examining the evidence, can still choose Keynes over Hayek

On October 17^th a group of concerned economists wrote to the Times. The current economic woes, they wrote, were down to insufficient spending/increased saving. “[W]hen a man economizes in consumption”, they argued, “and lets the fruit of his economy pile up in bank balances or even in the purchase of existing securities, the released real resources do not find a new home waiting for them.” Crucially, “In present conditions their entry into investment is blocked by lack of confidence.” The government should step in and spend to make up the shortfall they said.
On October 19^th another group of economists replied with their own letter to the Times. They believed that the cause of the economic problems was monetary mismanagement which had created “a deficiency of investment-a depression of the industries making for capital extension, &c., rather than of the industries making directly for consumption.” They argued for the necessity of increased saving to readjust this and explicitly rejected any role for government spending, writing that “many of the troubles of the world at the present time are due to imprudent borrowing and spending on the part of the public authorities.”
But this was October 1932 and the letters were written by John Maynard Keynes and Friedrich von Hayek. It says much about the essentially static nature of economic knowledge that an 80 year old debate remains so compelling today that it continues to inspire radio shows, debates, books, and even rap-offs..
