The offshoring race began when Ronnie Reagan made his speech to the nation in the 1980's where he said, "....... We're going to change our economy from a manufacturing-based economy - to a service-based economy." The "American" business community wanted dirt-cheap labor, so off to China, Singapore, Malaysia, Indonesia, India, Bangladesh, Mexico they flew. I'm old enough to have seen the speech, and watched as so-called "American" companies left in droves.
When dictator wannabe was prez, many companies he was going to "save" ----- left as well. This has been going on for decades. Without saying it in words, it's the "business community's" way of telling American workers, "You've been paid way too much, and you're lazy, so we're going elsewhere where we can run sweatshops 12 to 16 hours a day."
That dry pine-cone feeling in our butts is their gift to all of us ..... and our kids / grandkids. Truth hurts.
