Don't forget it also drains the international talent pool. There are great schools outside of the US; it would be foolish for companies not to hire from there.

Don't forget it also drains the international talent pool. There are great schools outside of the US; it would be foolish for companies not to hire from there. Keep in mind that if right now I wanted to hire: A smart graduate from EPFL, Polytechnique or ETH Zurich who interned at CERN and has contributed to the Linux kernel for a software engineering job at a unicorn startup or A grad from a second tier "technical college" in India with a visa refusal rate of ~90% for a job doing manual UI testing and QA for a body shop my only path forward is H1. They'll both be listed as "computer related occupations" and apply for the same visa in the same quota. Does that makes any sense to anyone?
