Federal reserve and fiscal policy are 1e9 times as important to job creation as this tariff. Would it be bad for the economy if someone invented a machine to make solar panels cheaply without any labor at all? No. That would be good because we could have lots of solar panels and save the planet.
Important to remember these tariffs were not conceived of as a job creation scheme. They were created to produce a windfall for investors who bought the bonds of bankrupt US solar companies. https://www.bloomberg.com/news/articles/2018-01-23/jpmorgan-...
I think that, for the White House, the tariffs have an added benefit of quashing an industry that more and more competes with coal. For reasons of graft, an obnoxious "heartland" brand and some weird fetishization, this administration is deeply obsessed with coal---one of the worst industries in the country to work for, which kills countless people via pollution.
