Because there are still considerable advantages to doing things the right way that make it worth doing.

I have a colleague in NYC who is like that, came from Eastern Europe to Canada and later the U.S. and he always harps on how unfair it is to his family and blah blah blah blah. I have never even told him my mom came here and brought six family members over straight and legal but literally none of us give a fuck about people who hop the border. No point in having the discussion because the guy is a fucking racist anyway. Every black athlete is some entitled punk and three Dominican kids walking to 7-11 for a Slurpee on a hot day are "thugs" to him. Gives you an idea of the type of person who thinks this way.
