The Musk supporters feel that universal automation is coming fast and I bet the Chinese being as industrious as they are will seize upon that to make up for their demographic issues. They are already he world leaders at renewables and nuclear and regardless, their ability to ramp up carbon based fuel sources is second to none.

Meanwhile the US appears to have an okay demographic pyramid(especially compared to their peers) but birth rates are declining and all the ingredients to increasing birthrate are not in the upswing (good incomes, cheap real estate, stable governance). Now you are killing off the US's golden goose (immigration) it seems like you are repeating the mistakes of China.

Hillary famously said "those jobs aren't coming back". I do not know if she was incorrect in that, but I suspect she might have been right. I don't see a viable path to that happening, and I've yet to hear anyone else describe such.
