Illegal immigrants pay more into social security than they take out. I don't even live in your country and I know this, come on - read a book.
Have a look at http://en.wikipedia.org/wiki/Zeituni_Onyango
She ignored deportation orders and managed to receive subsidized housing and a disability pension. She's not unique.
I think that comment was uncalled. If you wanted to point out OP disinformation you could just provided the source and it would be as much effective and also would be better appreciated.
My guess is it would be difficult to find any piece of document where it states something along the lines of "The goal of this program is to make this country more appealing for illegal immigrants, by offering them extensive welfare and preferential job and tuition situations, especially over those of our citizens."
I think what's more likely is that you are citing unfortunate byproducts of an imperfect solution to a complicated problem. Not a "typical reaction."
I'm not an expert on these things, though.
