It’s not just salaries.
Another problem is attracting prospective employees to blue states with sky high taxes, lousy schools.
H1B’s tend to be a lot less picky about where and how they live.
Which is great if you’re a blue state trying to keep your big biz from bugging out.
The ironic part is some of the biggest abusers of the H1-B visa program are Silicon Valley companies who are almost exclusively run by SJW Liberals...Facebook, Google, Twitter, etc......
