American system isn't perfect, and no system will ever be perfect, but its considerably better than being on a metallic standard.
Arguments sake, world was on Gold, a new tech came along, some interesting developments in energy storage with solar industry are in pipeline, and Element A was in high demand, eg Ta with mobile phones as past example. The Au standard constrains its growth to 10% annually with rest of econ at say 2% (current rate of mine, which itself does varies) - 0.1% (subtract little due to the weighted high growth of the new tech).
Element A would still be in high demand, Aust thinks well lets get these mines up and running asap instead of being cramped by how much Gold they have. They disconect from Au standard, fund their development with ease and so jump the competition and become global supplier with considerable lead time.
Any nation that goes back to a Gold standard will be left stranded.
