China was convenient because after Americans realized the level of pollution that our industries were causing, businesses decided to go get that dirt cheap unlimited labor and non existent pollution laws and Chinese-subsidized buying power.
That was all way cheaper than retrofitting our existing infrastructure, paying higher wages with less buying power of every dollar, dealing with pollution and safety laws, etc, so businesses went over there and Americans got a lot of stuff made for dirt cheap.
But this virus, and the understanding that we cannot go on trusting old supply lines, might be what leads to American businesses moving their industry back home. But it might end up with a whole lot of infrastructure (Robotics, building upgrades) and high end jobs but not a lot of line jobs.
It is crazy to think about how this might change everything.
