The idea of requiring a high salary is reasonable, but I'd make it rather e.g. 120% of the median salary in a particular industry.
If you can't find somebody skilled enough here to work for 200k or less, then you should probably be paying 200k or more since you're looking for a role that is niche and low supply.
To go further, I believe there’s good data on cost of living, geographically. It would probably be wise to use that in the formula as well, so as not to disadvantage smaller areas, where cost-of-living and salaries are lower.
The percentage could be reasonable, but I think it's too easily gamed. You just know the company would try and say they are bringing in entry level people for whatever they want and use whatever lowest median they could find. There needs to be a fairly significant minimum salary to avoid such monkey business.
An H1B job should be cushy. Otherwise, the company should simply raise salaries to find local workers.
The h1bs are often used to abuse that system by just importing someone willing to work for x, with the added bonus of it being very hard for them to ever leave your company.
But that would be a free market that respected human rights, and Americans don't want that! Equality? Freedom? That's just marketing!
So just open USA borders to anyone that passes screening (security / health / etc)?
What about gov subsidized welfare / healthcare / education / ...? Would you end all that? If not end it how would you handle the situation with current citizens vs the influx of foreigners who will expect these things be provided for them? And if those who show up start to vote for communism or some other ism that you do not like what will you do?
If you couldn't undercut H1B salaries there is little incentive to use them except for their desired purpose (you can't find any local workers).
"The proposal would increase the wage floor for H-1B visa recipients from $60,000 to $150,000, eliminate the Optional Practical Training (OPT) program, and replace the current lottery-based selection process with a highest-bidder system."

What I care about is the current system isn't being used to find hard to find labor, it's used to bring in cheap labor in an abusive situation.
We as a nation are really better off if we bring in the best in the world to work here with a cushy salary.

It is ridiculous. Do you have a citation for the $50K number?
