@Matchewed: Good post above. I agree with everything you said, except maybe to quibble about the 60k kids "not affecting us financially at all." The president has requested an additional $3.7 Billion just to deal with the kids crisis, above and beyond the regular budget to deal with illegal immigration. $3.7 Billion is a relative drop in the bucket of the overall federal budget, so you're probably right it won't really affect any of us very directly (maybe an additional $10 in taxes per taxpayer??? $100?? I pulled that out of my ass, I have no idea).
I can never help but wonder though how that money could be used to benefit poor citizens/residents that are here legally. We've got millions of American kids literally starving, homeless, or going without health care, and to me every dollar diverted to care for an illegal immigrant is a dollar that's not going to them. I don't mean we can turn a blind eye to these kids coming across the border but, like you said, it's something we've got to deal with in both a humanitarian way, and a way that sets up major deterrents to other people trying to come here illegally.
@Everyone Else: There are no two ways about it -- 99.9999% of the people coming here illegally are not self-supporting, certainly not at the outset. They have no jobs, no money, relatively no marketable skills beyond unskilled/cheap labor -- they come with nothing. They require free/subsidized housing, food, clothing, education, health care, and everything else a human being needs. They are a significant financial drain on certain areas of the country (mine is one). I have sympathy for their plights, but we should not fool ourselves to think there's no cost to feeding/housing/schooling millions of illegal border crossers via taxpayers and charitable outlets.
