There's not enough mined gold on earth, much less in US vaults, to go back to the gold standard in any reasonable way.

Not to mention, the entire financial system of the United States (and the world for that matter) is so convoluted, twisted and unintelligible that fixing it would be like forcing four Helen Keller clones to play Jenga, but no one told them how to play.

They'd be trying to figure out the rules of the game without bringing the whole game crashing down around them in the process.

Any process which doesn't end both the Federal Reserve AND Fractional Reserve Lending would be a failed process that would lead our nation right back into financial ruin. If you fix one, but not the other, then you've fixed nothing.
