Right wing oligarchs want infinite immigration because they get a larger labor pool and lower wages. Right wing normies want less immigration because they don't want to compete with the entire world for a job and don't want to become a minority in their own country.

Yet in the next thread over, people are crucifying DHH for saying the same thing, except they are spinning it as "denying their right to exist"... somehow.
