I'm assuming that someone wants us to draw the conclusion that this is a bad thing. But I don't see why our salaries should be kept at a high level, at the expense of both employers (and thus businesses and consumers) and other humans. Also, it seems to ignore the demographic problems that society is starting to see. Without a broader base of employed people, we can't keep paying retired people their Social Security and Medicare. An influx of employment-age people is necessary to keep these systems afloat. So in the long run, having these Visa workers will help ensure that I get out of those systems at least some of what I'm putting in.
