There's a vibrant high-tech contract manufacturing segment of the economy, led by behemoths like Foxconn and several other Asian players who specialize in consumer electronics & computing gear (Compal, Pegatron, Quanta, etc). That doesn't mean manufacturing doesn't exist in the US, though, and there are still very large EMS firms with significant presence domestically, like Jabil, Flex, Celestica, Sanmina, and plenty of others. The difference between now and 25 years ago is that it hasn't been cost effective to manufacture high volume, low complexity electronics in the US for a full generation. But, the majoarity of high complexity, low volume (NPI, very large PCBs, PCBs with many complex layers) stuff is still made in the west, and there will always be meaningful demand for high tech manufacturing in regulated industries (defense, medical), too. For example, CGMs are made in Alabama & Ireland, avionics for Apache helicopters are made in Alabama, data center server racks for Meta are assembled in Finland, Germany & San Jose. Same for Netflix CDN racks.

It goes on and on. The majority of what has been outsourced to China (and Taiwan and Singapore and India and Vietnam) is the "face" of high tech electronics, and the majority of electronic piece parts components, but not final assembly and not much of the tricky stuff. I don't think we'll see a quick ramp of high-vol/low-mix mfg coming back anytime soon because too much of the supply chain is in Asia, but it could if there were sufficient demand.
