In many parts of the US there is no where teens can hang out without spending money. My South Bronx neighborhood probably beats many cities, suburbs and small towns. (we have a skate park, and a larger park with benches-- though could use more options, for example a nicer library for kids who don't like noise)

In some towns libraries ban "teens congregating" playgrounds are out of bounds & groups of teens get the cops called on them.

This is the real reason young people don't go out anymore.
