A wild, disturbing, hilarious book that satirizes everybody. Activists, academics, politicians, white working class, black business people, etc. etc. no one is spared. It's got some flaws/blind spots beyond the typical things you'd expect for a book written in 1931 (its treatment of native americans is especially underdeveloped), but it is a very effective and creative mockery of the absurdity of race and racism. An interesting exploration of what the consequences would be for a fundamentally race-obsessed country if the black population disappears. The ending is especially crazy.
