On any given day, 75,000 Americans lose their jobs, and that is under normal circumstances. Industries and companies rise and fall, and there are always losers as well as winners. The result is constant 'churn,' with many jobs disappearing even as more new jobs are created. In an average month, there are 1.5 million “involuntary” job separations.
Trump's impact on Ford, Carrier etc. is meaningless.
