yes & no.
Yes - a third of the US workforce does need that, with a 350M population, but that was possible post-WWII ONLY because the U.S. had zero international competition, Europe was decimated to rubble, and Asia was pre-historic in industrial development.
Americans are too stupid to understand they are intrinsically fat, stupid, uneducated & lazy. They've lived high on the hog thanks to dreaded SOCIALISM: GI bill allowing university education post-WWII, social security, Medicare, unemployment insurance, and most importantly the only real manufacturers of ALL goods & services from 1945-1980 were US based.What u see with globalization today is the reality of America, 1945-1980 was an aberration....
