disruptive to whom most? Certainly not the American tax payers who shell out 65 billion dollars to these folks while the economy receives only about 20 billion dollars in direct return via legitimate taxes and other economic returns...As for diplomatic consequences...Central and South America hates us already!
I have serious doubts about those numbers that you're quoting. You have to look at the entire US economy, including all the extra income generated by American citizens because of the abundant low-cost labor of illegal immigrants. It's not an easy economic analysis to do. I'm researching this right now to post in a seperate thread. I'll ping you on that thread.
