The decline in quality of out Boeing has coincided with a collapse of the regulatory framework that kept profit extraction limited since the 70's and 80's. Now you've got the worst of both worlds, where the industry is protected and subsidized, production gets off-shored and outsourced anyway while massive profits flow into shareholders pockets in the form of stock buybacks. It's funny that you look at this and blame the protectionist aspect when "protectionism" literally built the industry in the first place.

Every country who isn't just getting exploited for their natural resources or labor has built their industry by protecting it.
