That's complete BS! They may not be entitled to it, but then how many people got into our country last year who were entitled to? Have you ever heard of false claims? Do you know how many people live in our country illegally? And I wonder how they get their money to survive... hmm, heard of false benefit claims??
I see it happen, it does happen, you're talking crap. I live in an area where there are lots of non-working immigrants (and lots of non-working english people too!). You obviously don't.
