I wouldn't use the words or examples that he used, but generally, do agree with the US is falling behind in STEM and it is, at least, partially due to our culture.
But there's a balance. The impression I get from below is he wants the US to be like the highly competitive Indian, Japanese, Asian etc. kids and I definitely do not want that extreme culture brought over to the US.
But yeah, we should do something more to encourage STEM if we want to remain competitive. Selective immigration is part of the answer. I do want more H1B visa, but do believe it needs to be revamped.
FWIW just a data point. I've met numerous locals in different countries; we talk about the US & politics & guns (and food!) etc.; often times they talk about how they are surprised and like how friendly, first to initiate talk etc. Americans are.
I know those Indians, Japanese, Chinese "nerds" don't do this near as much. Those Asian STEM superstars that I've seen (at least the first generation) generally lag behind in these social skills, and that is part of US culture I do not want to lose.
Also, to the point of jocks. Yeah, I want a healthy population of jocks in US sports. Soccer & cricket are boring as heck. And prom queens? Not as if those other STEM countries have great track record on women's rights and equal opportunities.
