So in his testimony to Congress today, Bernanke gets asked about the wisdom of letting the 2001 and 2003 Bush tax cuts expire. Bernanke said a) "there is the Keynesian effect of tax and spending," and b) "our tax system needs to be made more efficient." Let me translate: a) "raising taxes right now would make the economy worse," and b) "the tax system should be about promoting economic growth." Basic economics, gang. If only Congress would listen.
