American economists, central bankers and fiscal policy makers have reinterpreted British economist John Maynard Keynes’s clever idea that government spending is the best way to counteract a serious economic downturn — and have turned it into a permanent prescription. In their version of the Keynesian theory, declining growth or tumbling stock prices should prompt central banks to lower interest rates and governments to come to the rescue with economic stimulus programs. US economists call this “kick-starting” the economy.
….The only problem is that this method of encouraging growth has not stimulated the US economy in recent years, but in fact has put it on a crash course. From the Asian economic crisis to the Internet and subprime mortgage bubbles, economic stimulus programs by monetary and fiscal policy makers have regularly laid the groundwork for the next crash instead of encouraging sustainable growth. In the last decade, the volume of lending in the United States grew five times as fast as the real economy.
