“For all the troubles of the West, the US and the EU are coherent actors with deeply embedded institutional structures that are difficult to replicate. The costs associated with the introduction of the euro were unequally distributed among member states, but the vision of a common currency as a unifying symbol was seen to be worth the sacrifice. There is no similar shared vision between India, Brazil, China, Iran, Russia, and those other states that would allow for the replication of a common currency. For now, and for some time to come, the dollar is here to stay.”
