Why do illegal immigrants get government handouts?

i don't see why they get government aid and their kids get into collage much easier then normal american kids.. it pisses me off that a lot of them get away with it too! if we crossed over into mexico (who would want to) but just an example. legal americans would get in way more trouble then they do. if they do get caught all they get is a slap on the wrist sent back over where they can just cross back over again. I think they should start getting MUCH stricter laws on this
