Matt Stoller, "Goliath: The 100 Year War Between Democracy and Monopoly." EXTREMELY relevant book for our situation today.
Just finished Alex Gourevitch, "From Slavery to the Cooperative Commonwealth" - about how American workers in the Knights of Labor took republican theory (the theory of republics, not the party) and reshaped it to enable them to come up with a way to reform a modern industrial economy and restore democracy. They were eventually defeated, but anyone interested in the revival of republican theory in our time (authors like JA Pocock, Quentin Skinner and Philip Pettitt), should read this
Anyone unfamiliar with the theory of republics and what they are about - which is a CRUCIAL question right now, MUST read the VERY READABLE "The End of Kings: A History of Republics and Republicans" by William Everdell. A spoiler: Our second President, John Adams, wrote "A republic is a form of government in which POWER IS NOT VESTED IN ONE MAN."
