This book brilliantly connects the structural flaws of the 19th-century liberal order, specifically unregulated inequality and imperial competition, to the inevitable collapse that sparked World War I, the Russian Revolution, and the Great Depression, showing how these interconnected crises created a modern world defined by the violent extremes of capitalism, socialism, and fascism battling for dominance, ultimately leaving us with a flawed system carrying the seeds of today's wealth gap and political polarization that we still struggle to fix because we fail to adapt to rising inequality and technological change like the Soviet Union did by refusing to pivot from heavy industry to a tech-driven economy.
