That would be all governments.
As long as socialist states like India and Mexico are grossly subsidizing their societies' staples, housing, and fuel costs (like gasoline in Mexico), their workers can and do afford to accept much lower top-line comp. Our guys are competing with wage offers in Chittagong and Calcutta and Guadalajara, but the other side is subsidized.
American employers who offshore or import H-1/H-2/L-1 green-card foreign workers are effectively arbitraging top-line wages. It's a financial game set up by foreign societies' leaderships, and we need to break it up so our people can compete properly, on a level playing field.
Wages in Mexico, India and Burkina Faso are lower because their labor sucks. Americans are still the most productive workers in the world, which is why they earn more. H1/H2/L1 visa abuse is caused by government. Again, you're looking for government to solve a problem it created. Not what I would do, but I might also define insanity differently.
Finally, level playing field doesn't exist anywhere and it is absurd to think government is the institution that can provide it. Pollyannaish economics is no better than liberal economics.
