Not in the US. My experience is that immigrants, for example from India, are grossly underpaid. This would be for the software engineering area, and I've seen this over a two decade span.
Not disagreeing with what you say but there are people on both sides of the coin. For instance, myself and my peers (Indian graduates from a top 5 school in US) are extremely well compensated by our respective companies (well beyond the highest wage level defined by DOL). But due to the antiquated immigration system, everyone gets pooled into one bucket which results in decade+ long wait for a green card. I agree with you that the salary requirements need to be fixed and revised. Also, the allocation of the green cards can be done in descending order of the compensation of the employee instead of the country of birth/filing date system.
