I live in a big tech city and it's a very hot topic here on both sides. A lot of HB-1 visa holders are basically ghettoized in their companies and socially from the 'tech bro' workers who are from upper middle class white/asian families. They do a lot of the same work, but their wage differential is like a factor of 2-4x for the same job.

But true that it's not a big deal nationally, which seems to mostly focus on latin american emigration of uneducated low wage laborers.
