Keynes vs Hayek rematch

Usually sequels are pale imitations of the original, with rare exceptions (e.g., Godfather II, Terminator 2).  Last year economists at George Mason University produced a hip-hop video matching Keynes and Hayek to deliver the smackdown on macroeconomics. 

So now we have the sequel.  Do we need more government spending to increase GDP, or should the government just get out of everyone's way?  Watch and decide for yourself.  I generally avoid hip-hop like the plague so I cannot vouch for the music quality, only the economic arguments which are well-crafted on both sides and rhyme.
