I think it's an important question, and if the answer is "no" what can we do about it? It was this line of the article that resonated with me: "We are becoming a community where our teachers, our police, our firefighters, our nurses, they can’t live with us.

It seems terribly unhealthy to exclude the folks who provide vital and valuable services to a community from living in it.
Aristocracy is the norm for human civilization. I don't get why people are so chicken little about it. When your citizens are disgustingly wealthy they aren't going to have trouble buying those things.
