Not sure what your point is. "Concepts that have been proven in other countries are irrelevant here"? Or just "We have nothing to learn from what others have done and should start every idea from scratch"?

Your snarky summaries are actually extremely close to the sentiment I hear a lot.

A shocking amount of "political" thinking in the us that I've been involved with STARTS with "we're the best at everything" and then explores things to do from there

We collectively have this fragile ego that would rather feel tough and "self made" rather than admit any kind of deficit compared to others, even at the expense of our own growth. It reminds me of a ceo I used to work for that I flippantly described as happier to feel like a big fish in a small pond than to put his ego to the side in exchange for the ability to improve and expand the business.

Maybe we should try, as a nation, to stop being so intensely stupid and close minded.
