A study by the Brookings Institute asserts that visa workers actually make significantly more than their American peers in most categories.
There's a guy in my office that's on a worker visa- if you mention any of the stuff being spouted in this thread around him you had better brace yourself to be set straight with a lengthy dissertation from him. Another guy in our office was complaining about the proposed H1-B expansion within earshot and it turned into a 20 minute lecture. I have no problem with people who come into the country legally.
