I’ll let someone else point it out to you.
I happen to work for a company, one of the few, who exports half of its products to China. With the Trump promised 45% import tariff on imported goods from China, and, of course, the Chinese reciprocal duty on imported goods form the US, I, along with many others in our company, would be out of a job. The Chinese would buy from our German competitor rather than pay 45% more for our products, even though ours have proven superior performance.
I also happen to own two "sawzalls". One is US made and cost $120, the other Chinese and cost $20. They are located at two different sites, and I chose to own two, rather than carry one back and forth. For twenty bucks, it wasn't worth the trouble. They both perform equally well, for me, since I rarely use either. If I needed one regularly for my job, I would likely own a much more costly commercial version. If there were a 45% import tariff, the price of the Chinese one would probably double and I likely wouldn't have bought it.
So the Trump tariff would put me out of a job, a Chinese laborer out of a job, and there would be no increase in US jobs. There's a historical precedence for this, as well. The Smoot Hawley tariffs caused exactly the same situation in the '30s helping create the Great Depression. I didn't experience it, but I know it well. My mother, as a child, went to bed hungry many nights because her widowed mother couldn't find enough work to feed her children.
