There is no one whose a** we can’t kick if we quit trying to commit national suicide. This, however, won’t always be true it we get too far away from what our strengths are.
People need to remember why we have locks on our doors. Unfortunately we don’t live in an altruistic world, and others will take what we have if we let them. I trust us, as a nation, to be fair and charitable to the world. I don’t trust the world to be that way toward us. If we fall, they won’t pick us up.
You have that right.
And for posters lamenting the education of foreigners (and some staying here), well, look at our institutions of higher learning who love to rake in that foreign education money. Time was these foreigners stayed because the USA had a good program but now they go home because the President and his Science and Technology Adviser, John Holdren (look this guy up), want to level the playing field (and that can only suit the socialists in academic circles that take monthly junkets to foreign countries for endless cycles of meetings).
The problem is WE ARE NOT staying competitive! We are not.
