Imposing tariffs or threatening to do so and then backing off still has a disruptive effect on business.
Granted, but how much?
Even weather reports have disruptive effect on business. Every guru's opinion on CNBC or FOXBusiness affects business. Every opaque utterance from the Fed affects business.
The point is, how damaging are these tariffs, it seems incumbent on the Wall Street Journal which is notoriously offended by tariffs, to quantify these assertions.
