Wouldn't the most hardcore selfish anti-immigrant position not want people immigrating at all?
There are of course hardcore anti-immigrant people who advocate for the latter. That position is generally founded openly on sentimental nationalism and/or racism because it doesn’t make any economic sense.
Maybe net each one of these young people against a proposed H1B slot.
The complete lack of logic of the anti-knowledge worker immigrant position never ceases to amuse me.
