I agree that using illegals as employees is good for the consumer. It really sucks for the taxpayer, though.
And what about the case where the consumer and taxpayer are one and the same?
Far better to let wages among the legal population be determined by the market, and for the government to reduce or end many of the low wage subsidies such as the so-called Earned Income Tax Credit which now costs $60 billion per year, not to mention the additional billions of all government support programs that go to lower wage earners.
And my thoughts on the minimum wage is that it is about right, and that our nation and our economy is not especially well served by "entrepreneurs" whose enterprises cannot even pay the minimum wage to the employees they might need. Better off without them.
