Where I work, several people are on H1B's and they all make more than the prevailing wage. I'm immigrating to the U.S. and I had to be switched to an H1B from a TN visa for that purpose. I'm being paid about 40% more than the prevailing wage. All of our salaries had to be posted in the breakroom so everyone known we are not being hired as a wage savings tool. That doesn't mean that there aren't boiler room employers that do that. If you know of any, report them to the Department of Labor. They set the prevailing wages.
Agreed 100%.
