Central banks screwing up

The Triffin dilemma or Triffin paradox is the conflict of economic interests that arises between short-term domestic and long-term international objectives for countries whose currencies serve as global reserve currencies. This dilemma was first identified in the 1960s by Belgian-American economist Robert Triffin, who pointed out that the country whose currency, being the global reserve currency, foreign nations wish to hold, must be willing to supply the world with an extra supply of its currency to fulfill world demand for these foreign exchange reserves, thus leading to a trade deficit.

The world needs a reserve currency. If the American socialist government  agrees to provide the service, then Congress will run continual deficits justifying by noting the foreign demand.

Free traders foul this up, claiming the reserve currency functions are neutral.  Instead we get  sudden rebalance by  large default, as we did in 1973.  Thus is what I mean when we need the complete set of tariffs, internal and external and  balance the whole set.
