Paying them to leave is a good idea... could we pay leftists to move to Cuba, North Korea or something??
Send them there on scholarships for advanced degrees. If only a few of them have an epiphany and come back anti-commie, it’ll be worth it. If none of them do, at least they’ll be out of the country, and maybe they’ll shack up with someone special and decide to stay and pick rice or some damned thing for the rest of their lives.
