$113,000,000,000 per year? That is 113 BILLION dollars.
I believe I found the study you were referring to. Several problems with simply quoting this study as an explanation of the problem of illegal immigration.
1. There is an equally well founded study that shows illegals are a net boon to our economy. Since the problem remains a little studied one, and since the two main studies are directly contradictory, quoting either as an "answer" would be fallacious.
2. But lets say, for the sake of discussion, that this study is the correct one. It still isn't an answer to the question of why *illegal* immigration is a problem. Why? Because this same study shows that the fact that these people are here illegally means that the cost to America is actually *less* than if they were legal. So, if the immigration laws were such that all these same people had come here legally, the cost to American would actually be more than it is now (according to the estimates of this same study).
Thus, the study is cannot be used as an argument against illegal immigration, but against immigration of poorer people PERIOD! If the levels of immigration are ignored, then its actually cheaper to have them here illegally. Thus, this study, even if correct in its estimates, is by no means an argument against illegal immigration, but against letting poor immigrants come here at all.
3. And that doesn't even begin to touch on the fact that a very large portion of these expenses are the direct result of our welfare laws. Do away with those sorts of programs (or restrict them more) and a very large part of these costs disappear. Thus, the expenses are not even primarily about poor people immigrating but about our system of laws which likes to redistribute wealth.
Its fallacious to blame the 113 billion on the illegals when
a. its not even clear that 113 is at all accurate
b. even if it is accurate its still less than if they were hear legally
c. even if it is accurate, its at least half the fault of those who allow such welfare laws to be passed (ie. the American people).
So, my question still stands - whats the problem with *illegal* immigration?
