Quality of production is determined by the manufacturer's specs for the job.
The Chinese make quality and they make crap, same as American workers.
Americans make crap too. I've bought Made In USA stuff that has been junk.
Most of the parts in the American cars are made overseas now.
The majority of Ford Truck parts are made either in Mexico or other countries.
Lack of foreign competition prior to Japan becoming a big player just made American car companies fat and lazy and they made junk.
