All the pieces matter. Season 2 is knocked until you understand the show as an anthology of how public and private Institutions systemically extract wealth from inner cities and are allc9mplicit in not solving problems.
The local drug trade
The loss of blue collar jobs and international crime
The politicians and police bureaacracy
The school systems
The press
Each group trying to survive by failing the people they should be helping.
Plus it is well written, well acted and surprisingly funny.
