That data is extremely skimpy. Where is the comparative data? All I saw was one figure, "prevailing wage". What is the sample size? Is the sample based on workers operating in the same region (for example a company with multiple locations could very well cite a domestic salary relative to all locations (bringing the average down) or cite numbers from the cheapest region. etc. etc. etc. There are a many ways to lie with statistics and the number of ways you can lie with them is inversely proportional to the quantity of statistics released.

For example, the first petition I clicked on was very fishy: https://icert.doleta.gov/index.cfm?event=ehLCJRExternal.dspC...

$96k-116k offered for an engineering position that requires a master's degree and where the prevailing wage is quoted at $92k!?

I want to see real numbers her.

Look up the methodology, it's on the Department of Labors website. Are you suggesting that the gov't is conspiring to keep wages low?
