This biography was incredibly detailed and thoroughly researched. I know woefully little about the history of labor struggles in the US, this filled in a lot of holes in my understanding. I read a LOT of non-fiction and history books, but didn't previously know that over time labor split from civil rights activism, to narrowly focus on specialty interests confined to the workplace.
A great primer on the differences between Communism and Socialism, activism and revolution, and the factions of Black civil rights groups.
I may have to buy this one and underline the crap out of it. Highly recommended for history geeks, labor scholars, and anyone interested in the struggle to make America live up to its promise of liberty and justice FOR ALL.
