He is addressing the problem. Please stop pawning it off as political theater and McCarthyism. It sounds like the facile bitterness of someone reticent to admit an enemy was right. As Charlie said, he was addressing Greenspan´s ideology and the spread of his Randian, free market, deregulated policies that were bad for American (and absolutely spot on. Admit it! Swallow the bitter pill.) Who better to address and to expose than right wing ideologue hero and mentor, Greenspan, in an attempt to change the mind of the right wing legislators of the Bush regime who thought it was good policy to lower taxes during two wars and deregulate the financial industry to such an extent . . . and of course eventually socialize the losses of their short, greed-sighted economic ideology.
You perfectly illustrate the problem with the right wing ideologues that make it so difficult to change legislation. Instead of giving Sanders his due, you continue to mimic each other calling him a commie, a know nothing on the economy that is a McCarthyite who selfishly and foolishly creates political theater, and will always start up with the same tired wealth redistribution rhetoric.
