This is the most clueless take here.

It is so obviously not zero sum. From Google to Yahoo to eBay to Palantir. None of those hundreds of thousands of jobs would exist without immigrants. Or they would be overseas.

I'm sorry for your friends who cannot get tech jobs. It's time to level up their skills. No competent developer can't find a job in this economy.

Stop blaming immigrants for your own shortcomings.
