My guess is that all these foreign grad students entered the country legally; got an excellent education in their countries rather than the pap taught in our public schools grade one through college. The misinformation, intimidation, viciousness, of social media, wasting hours of real learning to gain what?...brain dead generations who will fail in competition with brighter and harder working people from around the world...and sadly procreate future generations and knowing little better, raise equally brain dead children.
"foreign grad students entered the country legally; got an excellent education in their countries rather than the pap taught in our public schools grade one through college."
You make a great point. Foreign K-12 is focused on straight math, science, and language. I pity, absolutely pity, American school children with the useless crap that is packed into their heads. Truthfully, the most useful skills to be taught to youngsters in readin', writin' and 'rithmetic. Most of the poor public school youngster's day is packed with propoganda and brainwashing.
And it only gets worse at the college level. STEM takes a lot of work. Foreign countries don't saddle their engineers with unrelated propoganda "core" courses designed to idelogically indocrinate. American undergrad students are forced to take courses on "divirsity' and other useless ephemera.
