Richard Reeves would agree that black men and boys are disadvantaged (with outcomes significantly worse than black girls say). In the interview with Ezra Klein he focuses quite bit on this disenfranchisement, and says how the political right neglects disadvantages that uniquely impact race, and the political left neglects disadvantages to men, and the end result is that neither care about the plight of black men.

That both parties neglect the cause of black men is (in my opinion) an outcome of a two party system that is so divisive that it leaves no space for nuance (and poor policies and extra needless human misery is the result).

True voting reform (e.g. STV) would percolate thru the system in myriad ways.
