The sad fact is that anyone who permanently resides here (legally, illegally, or otherwise) must be assimilated into the mainstream because the alternative is much much worse: A vast growing subculture of fugitives (by definition) hiding from the law, feeding a life draining underground economy, stealing to live and then turning to other, more worse crimes like selling drugs to our kids and breaking/entering into our homes, using our medical and other facilities paid for by our taxes, never paying taxes, not getting educated, not contributing to society in a positive way, hating the society around them (you, me, our families).....
That's the way it is (we allowed this to happen) and we can point finger all day long, but the political, social, cultural, and other realities have to be faced.
