Also, a return to the gold standard would be a very bad idea. It sounds great at first because there is at least something tangible to back the currency, and makes it difficult to increase the money supply (which hyperinflation is caused by an increase in the money supply). But the value of gold fluctuates too.

Also, if we returned to a gold standard, it would allow gold hoarders to manipulate the money supply. That's not just in the US, but around the world. Do you want the Chinese to hoard gold and disrupt our economy?

It is better that we put the trust in central bankers and expect them to responsibly discharge their EXPLICIT duty of maintaining the stability of a fiat money supply.

Bad idea. It would lead to massive inflation around the world.

For example, when Italy went from the Lira to the Euro, it caused massive inflation. The Euro was worth a lot more than the Lira and when the switch was made, the price of a good that cost 3 Lira, now cost 3 Euros. The cost of living went extremely high in a country that was already expensive to live in.

Also, it would increase the buying power of China drastically. If the Yuan was replaced with this new global currency, their wealth would increase at least 3 fold. Of course, it would be cost-prohibitive to import Chinese goods, but it would still be a massive gain for China, and a massive loss for the US.
