When I used to live in the Mission District of San Francisco, sometimes "poor, urban" type people would stand around on the sidewalk and street in front of my window and yell at each other for hours in the early in the morning. (My guess is it had something to do with pimping and prostitution.) If I lived in an outer suburb of San Francisco (Walnut Creek miles from a BART station for example), people like that would have a hard time getting to my street, because most of them do not have cars; and since there would be nothing near my home besides other homes, it would be a boring environment for them unless perhaps they are into jogging or walking their dog or something like that. Ditto the people who used to park across the street and play their car stereo really loud. And the guy with the pick-up truck who was helping his friend move and left his car alarm on the most sensitive setting, so that it would go off every time a car passed by it. The French and other nations on the continent of Europe are much more accepting than Americans of the use various policing, administrative and legal procedures to encourage the aforementioned individuals to stop the aforementioned behaviors and conform to a quieter or more conventional patterns of behavior. This is an example of what I meant when I said that Europeans tolerate more onerous restrictions on individual liberty than Americans do, and this is a significant part of why IMO wealthy people in France mostly consider the core of Paris a nice place to live whereas wealthy people in the U.S. mostly do not want to live in American inner cities -- at least they do not want to after they turn 30 or so.
