He's absolutely right. The biggest pro-immigration retards, both on the right and the left, are basically arguing in favor of keeping a low-IQ brown slave caste. Illegal immigrants and legal ones. The only difference is the shade of brown they are. "The price of your avocados will go up, so we actually have to keep mass importing rapey Mexicans" is the same as "Um, we need to pay coders less to do more and Americans aren't retarded enough to do it, so we actually need to import more rapey Pajeets."
The only problem that can be solved by throwing brown people at it would be if we had a coal shortage and needed something to burn for warmth.
