do you want a permanent underclass of people who have no *legal* way of making a living? when the only options people have are violent crime or starving to death, then they're not going to just give up and die for the convenience of a society that offers them nothing. only an idiot or an american - but i repeat myself - would think that is a good thing.
OTOH if they are given a chance to become part of normal society then all but a handful of the seriously fucked up and psychopaths (most of whom will shortly be back in jail) will settle down into relatively peaceful, normal lives.
the fact that the law permits such discrimination is the problem - as i said, except for some very obvious exceptions that ought to be as illegal as discrimination based on colour of skin or sexual orientation.
btw, you can shove your obvious over-compensation for your inferiority complex up your arse - the notion of american superiority is laughable. you've got more guns and more violent crime than anywhere else but you're trailing the world in pretty much everything else. i wouldn't even want to visit your fucked up fascist police state of a country, let alone live in it.
