First of all, there is ghettos INSIDE Paris too:18th, 19th, 20th districts....

Transit lines are not used to confine them to the suburbs, they're the only thing allowing them to actually have any opportunities.

As a poor student I lived in a rich Parisian neighborhood and I also lived in a very poor suburb. I definitely preferred living in comfortable housing with a 40min commute than in a closet with a 10min commute.

There is some places where there is actually no opportunities because of the LACK of public transportation, like in some neighbors in the north of Marseille where there is 80% unemployment.
