There's no reason to return to the gold standard. For all the growth that we could achieve through his economic & fiscal policies, it would be limited by implementing the gold standard. Going to the gold standard is a purely ideological viewpoint and not at all feasible in this advanced of an economy.
Anyways, gold is like, so 1992. Might as well be drinking Taqueray and ridin' on Dayton rims. Platinum is where it's at, baby!
