Also, if you read it now, it hasn't aged well.
Namely, how the piece talks about his community in Harlem. The language was appropriate for the time, progressive even, but isn't now. Think Mame.
On a side note, and very generally speaking, I've unfortunately concluded that progressive art ages worse than conservative art. While conservative art is often blithely ignorant to injustice or suffering, generally, progressive art that seeks to acknowledge injustice therefor included language, views and solutions that are inspirational for the moment, but date quickly.
