Prepare to observe the spectacle of the two great economic paradigms of the twentieth century crashing to the ground, locked in mortal combat.
A hundred years past, markets ruled freely: fortunes were made, workers abused, bubbles blown. According to the Austrian School of economists, led by Ludwig von Mises, this was all as it should be: despite any temporary pain or inconvenience, the unfettered market always knows best how to allocate goods and organize investment and labor.
But the ensuing pain and inconvenience were just too much for the various stripes of Marxists and socialists, some of whom led a revolution in Russia to establish the first state-controlled, planned economy.
The catastrophes of the Great War and the Great Depression led to the ascendancy of John Maynard Keynes, the British economist who argued that even capitalist economies needed regulation and controls in order to avoid excessive manias and subsequent implosions.

Now with the Collapse of 2008, economists are rushing to announce a new era of neo-Keynesianism: lack of regulation in the finance industry has led to a cataclysm of unimaginable proportions, and only massive government intervention can put us back on track. Sadly, this time the tracks have been moved, maybe dismantled altogether. The two great economic paradigms of our age simply took too much for granted. They assumed that economies run on money and labor, whereas real economies also need energy and natural resources. They assumed that because population, resource extraction, and available energy had grown throughout the 19th and 20th centuries, they would continue to grow in perpetuity; all that was necessary was to properly adjust the relations between money, market forces, and government regulation. No one (within the economics profession) stopped to think that limits to Earth's supplies of fossil fuels, topsoil, water, and other resources might impose ultimate limits on economic activity.
