One if one ignores the laws of this country regarding min wage and overtime. Just because you feel that laws should be ignored, doesn't mean that they should.
It's nice to see that you support those that break the law, simply so they can make profit. Let me ask you this, is a US citizen who isn't on welfare being replaced by an illegal who is subsidized by the US Taxpayer a good thing?
The fact remains, if a good (labor) is available at a lesser price for the same thing, the higher priced good (worker) is overpriced, by definition.
Goods and labor only sell for what the market will bear. The labor market in the US is now waking up to the fact that its prices were artificially high.
