Perhaps instead of a tariff it may be better to have a law that makes it illegal to close factories. Well of course if none of those fabled 100,000 factories, nice round number that it is, had left employment may be a little higher. But they would have still drastically curtailed employment.
Again industrial output is at near record levels maybe it could be higher but jobs are going to continue to decline. Higher employment costs means less jobs and more robots and automation. Many US workers are priced out of the labor market thanks to the myriad government rules and regulations and industry protection rackets such as sugar tariffs.
Be flippant you a$$hole. The American people have had enough of “Free Trade”.
