Has nothing to do with it.
Has everything to do with expanding the aerospace manufacturing base of this country instead of farming work out to the Chinese as Boeing so proudly claims on their website.
“Since the 1980s, Boeing has purchased more than US$1 billion in aviation hardware and services from China. Today, Boeing and Boeing supplier partners have active supplier contracts with China’s aviation industry valued at well over $2.5 billion. Today, there are more than 4500 Boeing airplanes flying throughout the world with parts and assemblies built by China.”
Might also note that MDC was doing business in China before being kidnapped by Boeing.
And, If Lockheed was still in the commercial AC business, they'd be there just as heavily as the big two.
