I have some weird questions. Do people in the various boroughs of NYC,

[Backseat Driver]

not the State of New York, exhibit a lot of rivalry/competitiveness with each other based solely on their borough of their residency or more along the line of religious/nationality/racial characteristics 1)within NYC; 2)within a particular neighborhood of their borough? Do they have an "I don't want to live there because..." Were the crime families ecumenical in their exploitations in each borough, having a larger regional boss, or "different" leadership bosses assigned to the neighborhoods/boroughs?

I find it odd that persons born/raised/residing in NYC's particular boroughs as children or young adults don't seem to have associated with "rising stars" or have been "mentored" by leaders, corporate, in the "trades," political, or criminal in other neighborhoods.

I've never been to NYC and probably would not attempt it without a native guide, so help me understand various characteristics of the citizenry there.
