"...We even deal with illiteracy now. How do you think illiterate people can compete?"
Bush/Bayourod open borders bring in millions of functional illiterates, they maintain that this makes us more competitive.
It's a good point: the average literacy level does decrease, as you pointed out. But, to the best of my knowledge, the proponents of open borders do not justifhy it by better competitiveness: they point out that they increase our standard of living (cheaper labor, cheaper products, more of them we can buy).
I am not saying they are correct: Bush and Co. only point to private goods and services like groceries and lawn care, and, although the cost of these does go down, the cost of public goods goes up (roads, emergency rooms full of illegals, our schools for which they do no pay a dime, etc.)
I am completely with you on this: I cannot find a single reason or excuse for not shutting close all of our borders. And, although I am distrustful of government, I would even accept an national ID card if it really helped to drive the illegals out. But that is not going to happen: all dems and even some conservatives are wobbly on this issue, right?
