We live in a golden age of economic debunkery; fallacious doctrines have been dropping like flies. No, monetary expansion needn’t cause hyperinflation. No, budget deficits in a depressed economy don’t cause soaring interest rates. No, slashing spending doesn’t create jobs. No, economic growth doesn’t collapse when debt exceeds 90 percent of G.D.P.
And now the latest myth bites the dust: No, “economic policy uncertainty” — created, it goes without saying, by That Man in the White House — isn’t holding back the recovery.
