Pre-covid unemployment was almost too low. Considering we've had tightened border policies, if by magic we could bring these jobs back to the US who would do them? It was speculated that if these jobs came back within a short amount of time we'd see inflation and interest rates that would make Jimmy Carter blush.Sorry, the real lesson is that globalism has moved so much manufacturing out of the US that we are really dealing with the fact that without workers and their incomes you have no consumers. In this case covid and shutdowns drove the point that everybody is trying mightily to ignore. Service industries alone don't get it; you have to have manufacturing; you have to put in labor (sweat equity) to make something worth more than the sum of the material input. Wealth is derived from the labor and the ingenuity used to turn raw materials into a finished product.
If you're really worried about manufacturing, worry about the robots.
It's estimated 57% of all these jobs can be eliminated in the next 20 years. Honestly, I think these numbers are conservative. Computing power is doubling every 18 months.
