One thing that could cause this loss of faith to occur is if the Chinese are successful with making their new E-currency a medium of exchange for Americans.

My understanding is that the modern monetary theorists have an argument as to why this hyperinflation won't happen in a country with monetary sovereignty. (All the famous historical examples of hyperinflation involve countries that do not control their own currency.)

Damned if I can find a good basic text explaining the MMT argument. Naked Capitalism makes some great allusions but seems like you need to already be on their team to understand their arguments.

Seems pretty important to understand this stuff as we are all modern monetary theorists now whether we like it or not.
