There are two issues here:
1) Is automation going to be a problem for the US? Will there be too few jobs for Americans as industry becomes increasingly modernized? I would say “yes”.
2) Should China be allowed to take advantage of us though unfair trade practices, intellectual property theft, and currency manipulation? I would say “no”.
The two issues have no serious overlap. A mathematician would say that are “orthogonal”.
I don't think so.
Someone has to build the robots and program the software. Based on the performance and durability of modern day electronics, the robots will have to be upgraded/replaced once a year. The software will undergo neverending revisions. Takes people to do that.
Automation will only be a problem if the factories are not in the USA. If in the USA then they will crate wealth for all AMERICANS.
