You honestly believe and are arguing in good faith that higher union membership drives down overall GDP but has a minimal impact on workers share of the economy INSTEAD OF higher union membership keeping the 1% from accumulating ALL of the economic benefits and growth at the expense of everyone else?

You realize GDP didn't just magically start growing in 1979 with the slow decline of the union (itself a coordinated campaign from the right)? http://www.shadowstats.com/imgs/2011/680/image006.gif

At this point, with all of the economic evidence that exists regarding the benefits to workers of strong unions, to argue against them you're either brainwashed by AM radio and Fox News, being dishonest, and/or don't have most people's interests in mind.
