I'm going to step aside from the political aspects of this, and look at what "Made in USA" means as an indication of product quality.
When it comes to electronics, Asia is it. The electronics industry and supply chain has become so concentrated in Asia that it's hard to even build electronics anywhere else. You can assemble a Mac Pro in Texas or a Raspberry Pi in England (in a Sony plant!), but most of the parts will still have to come from somewhere in Asia.
For mechanical things, though... For mass-produced items that require mechanical smoothness and nice fit-and-finish, I think the top signs of quality are still "Made in USA" and "Made in Japan". The Japanese are almost fanatically proud of their manufacturing consistency and quality control. As for the USA, all the manufacturers whose first concern was cutting costs and cutting corners have already gone overseas back in the 1990s, and those who stayed here are the very best.
I got the impression that British and European products are generally quite good, but their QC can be spotty. As for China... The quality standards of Chinese products is all over the map, from abysmal to excellent, just like it was in the USA back in the Good Old Days when most stuff was made here.
