I don't think most of our hucksters really believe in their bullshit, they just want tax cuts and free money for rich people and will invoke any argument to achieve that goal. They don't really care if such policies grow the economy or not, because they don't care about the economy. They care about the pocketbooks of themselves and their friends and their donors and the general Galtian Overlord class.
In Yurp, however, it seems some of the "technocrats" do actually believe that through the widespread application of leeches to the moochers and parasites, every country can magically run a trade surplus. Or something.
