I don't like that immigration is framed as a left-center vs right issue. Around 1900 the socialists were against immigration because it displaced local workers and capitalists used it to drive down wages.

So, ironically, Paul Graham supports the right wing position and Luckey the left-center if you frame it that way!

The most qualified for physical jobs are the healthiest. By allowing unlimited immigration, you literally let in the healthiest and most persistent to the detriment of less healthy locals. Eugenics? You can frame it that way, too.

Being born in a desirable country has disadvantages now. People from all over the world buy property and drive up prices, people from all over the world compete for local jobs, take university places (almost free in the EU). That is locust capitalism and the distinction between the von Brauns and the regular H1Bs that the article makes is sensible.
