It's not worth discussing this because the reasons are well documented.

You need to adjust for cost of living, universities, hospitals, non profits don't pay as much etc.

There is a prevailing wage determination check for granting a H1. That rule was revised a few times, that's the right lever to pull.

You could make the prevailing wage requirements == median wage for a given experience in an area. Right now it's the 35th percentile.
