We need a good trade war. It would put people back to work. If there is not enough gold then make it a part gold and part silver backing for the dollar. Just don't nationalize all gold and silver mines.
A bi-metallic monetary standard won't work. That's been proven right here.
Pick one metal and let the value float is the only way. Trying to peg a value instead of a certain weight causes all sorts of problems.
That doesn't mean that both metals couldn't circulate, however. The other could be used in a non-official manner, and silver would fit that requirement nicely. Imagine one ounce trade dollars being put into circulation by approved sources with uniform sizes and weights to make picking counterfeits out really easy.
In this debate I listen to the real expert: Jim Rickards. He advocates a partial Gold Standard. That makes sense given the dollar level that Gold would rise to given a 100% backing. Rickards has not been all that visible (or vocal) lately, which I find interesting, but here is his latest piece that I can find on the subject.
