gated communities

I was listening to an interview on NPR yesterday with a guy whose dad is one of the richest guys in Rissia.  He lives in a gated community, which is quite common.  Do we want that?  Should police and fire be privatized?  Should the wealthy just hang out in their wealthy gated neighborhoods, and people (the 99%), just come and go to do work, like Palestinians going through checkpoints in Israel?  Is that what we want?
