Newark NJ high rent neighborhood garbage quality of life no community or city clean-up away downtown

Noticed a neighborhood in Newark, New Jersey just at chance to video how can new buildings have high rents with such problems in community or city neglect. New building with trash nearby and not cleaned exterior. Old empty lot with trash and no clean-up from neighbors or other landlords. High rent apartments with renters not caring of the neighborhood and seeing trash along the boundaries. What would be your quality of life?
