However, in 1945, Europe and Japan figured out how to build non-exploding factories. The trade barriers were also removed. We retained our competitive advantage for some time after that, since it took them time to build up an industrial base.
But it is silly to expect us to be world leaders to the extent we were back then. That epidemic of factory explosions was a one time occurrence.
We've been outsourcing not just blue-collar work, but more and more white-collar work as well. While this is essentially inevitable, it will, in the end, demote America to a second-world country, divided into starkly wealthy areas and dirt poor areas.
There is a healthy distrust of elites claiming authority on the basis of intellect and education. "We are in charge because we're smarter than you and know how to take care of you" really does fly in a lot of other countries. Call it "Mandarinism"; its hallmark is examinations and elite institutions. In America, opposition to this sort of thing goes back to the defeat of the Hamiltonians.
As for a general disdain for intellectual pursuits in the culture at large, that's just a bunch of bullshit. It's no different from any other country once you take demographics into account.
Trust me, there really is a strange element of anti-intellectualism in America.
I've lived in various countries over 8 years and am otherwise well travelled. I say there's no difference. The popular media is a bit more dumbed down in the US, but that's no reflection of the intellectual pursuits of people in general.
