I say "Republican Economics" because it's the status-quo Republicans who make the most noise about this, although the Dems do so too, it's more of a back-burner issue. If I recall, all Republican candidates, except Paul, Huntsman, and Johnson (now Libertarian) spouted this nonsense.
The issue I am getting to is this tosh about how China is a currency manipulator, and how it is hurting the American middle-class (we hear the same bullshit in Britain, too).
I even remember Romney stating that he might impose a tax on China to counter-balance their currency manipulation. If you get rid of the political double speak, he effectively said "I want to help the middle class by making it more expensive to buy a lot of the products that they need to purchase".
And the crowd loved it (this is during the early GOP debates), they ate it up.
It was around that time, btw, that I gave up hope of anything good coming out of the 2012 Presidential election. We're seeing some good stuff in the Congressionals, and, hopefully, State elections... Presidential, and the rest of Congress will be utter tripe, again.
