Yeah, you should disallow that. If you push them out, then Joe SixPack would be able to make much more money for writing JS and Ruby code and bring US economy forward.
1) You SHOULD disallow that. Why tolerate a system that creates incentives for that kind of abuse.
2) "dirty immigrant bastards" - You're assigning a point of view that the commenter isn't advocating at all. Protectionism is generally more about looking into the future and being scared for your ability to continue at your standard of living and less about disliking certain kinds of people.
And to add my own anecdote to this discussion without siding with anyone else's viewpoint (because I'm a special snowflake with my own nuanced opinions): I've worked at companies that chronically underpay H1B workers. The ones that got fair pay were the ones that were brave enough to demand it.
That is really a different issue. The law says that there is a baseline salary to be met. Now anything above that is what the employee should be negotiating. There are enough American/women/$minority engineers who get underpaid because they suck at negotiating. That doesn't necessarily mean discrimination exists.
Policies for people, written by corporations. Clearly this is a good thing for us long term.
Wow so off base its funny, that's the blanking problem.
