I have news for you. While it is true that the liberal arts colleges are producing minds full of mush, there are tons of great technical colleges and universities that are turning out extremely talented American engineers.
The problem is that Musk and other cheap labor tech magnates will hire Americans first because they can get H1B indentured servants for a fraction of the salary that they would offer an American who could freely leave a job without having to move out of the US.
Maybe you’re okay with replacing our next generation of talented engineers with foreigners, but I’m not.
