Interesting illustration of economic spectrum:
To the left is Austrian school of economics, in which the role of government in the economy is limited (Friedrich Hayek & Ron Paul).
Then the Monetarist school (J.P. Morgan, Ben Bernanke) and the Keynesian school (John Maynard Keynes, and Barack Obama), both characterised by big government spending.
And finally at the end is the grand daddy of all big government, the Communist school of economics (Karl Marx, Kim Jong Il).
