Then they should have done some research about the neighborhood they were moving into.
In all of America there are actual laws against littering, noise and pollution and wherever I move I expect them to be enforced.
Also I wonder if these lawbreakers were respectful of the culture that existed prior to them arriving? I doubt it and with that I will conclude that they probably don't deserve the same respect. It's a free country you know? If they don't like it they can move somewhere else (and probably disrupt wherever they move to).
I've been on the receiving end of car heads moving into my neighborhood. I ended up having to move out. What goes around, comes around I guess.
If a bunch of people like me moved into town and started complaining, we probably could have gotten rid of those lowly pests that moved next door to me.
Since that wasn't happening anytime soon, I figured the next best thing is to just use some of my high income to move to a place where these kinds of lower class people can't afford to live and that's exactly what I did. I saved plenty of money living in a lower class neighborhood for a long time and the market conditions were totally right for a move so in the end, I actually won.
