How long until countries with failing national systems are simply brought into the U.S. monetary system, with the USD supplanting their national currencies and their central banks becoming the equivalent of a regional Fed bank in the U.S? The sooner the better, I say. Would that not help to alleviate the source of the flow of people seeking to migrate from such nations to the U.S., etc.? Better for all concerned to subsidize (cheaply) their lives in those nations through national programs (clean energy, health care, housing, education, transportation) funded via speculators via the Fed.
