If having millions of cheap workers were the way to build wealth, most of Africa, Asia, and South America would be rich now. In reality, a large supply of low-skilled laborers is merely a way to have a class system where the monied and connected elites can stay on top and have little worry about the underclass removing them. There are PLENTY of such examples in Africa, Asia, and South America. Is this what Bush really wants?
Well must not be about building wealth but a 'compassionate' method of spreading and maintaining some peoples wealth. Because the liberal minded are NOT going to ignore the supposed plight of the underclass, they will find a way to transfer the wealth using the tax code.
