The problem is - tax and spend is fully supported by our Federal Reserve. An unbacked, fiat currency, issued by a Federal Reserve that can manipulate interest rates, create money out of nowhere, and buy up debt gives politicians carte blanche to run all the leftist political and social-engineering schemes they want.
Fully supported by the earth too, without the planet the entire federal government would drift into space until it fell into the sun. As for national policy I'd much rather be watching both the earth and the Federal Reserve supporting tax cuts and a respect for private property that would let America create wealth at the rates we had in past decades.
Then we can let governments all over the world "manipulate interest rates, create money out of nowhere" like they've been doing for centuries.
Until they can't. And then, all hell breaks loose.
