Sometimes you have to be brought back to reality and realize that the vast, vast majority of USAmericans have not grappled with materialism, thus nearly all the connections they make are like a 6th grader writing out their 5 paragraph essay for the high stakes exam that determines if their school gets funding or not.
US self made brain drain is going to hit the country like a comically large boomerang, it already has essentially.
Yeah, even if a person gets an undergrad degree they still have the capitalist brainworms unless they poison them with theory. Reading and writing education in the US is so formulaic as to be worthless. People are taught to follow a small set of rules and if they don't follow the rules, they fail. They are not expected to think. Even so, many people refuse to read or write anything, either paying others to do it for them or just turning in some AI slop without taking a single look at it.
Yes and no. We used to actively court immigrant intellectuals, now we're accusing every Chinese intellectual of espionage and frothing at the mouth to deport anyone darker than freshly fallen snow. People with advanced degrees see what's happening in the US and are choosing to go elsewhere.
Slightly more seriously, the people who can actually do things will go to countries where they can actually do them. The US ripping the copper wire out of everything will reverse any sort of intellectual dominance that it once had.
