WHY WE'RE POLARIZED

America's political system isn't broken. The truth is scarier: it's working exactly as designed. In Why We're Polarized, Ezra Klein reveals the structural and psychological forces behind America's deep political divisions, revealing how a system filled with rational, functional parts can combine into a dysfunctional whole. Neither a polemic nor a lament, this book offers a clear framework for understanding everything from Trump's rise to the Democratic Party's leftward shift to the politicisation of everyday culture. Klein shows how and why American politics polarised in the twentieth century, what that polarisation did to Americans' views of the world and one another, and how feedback loops between polarised political identities and polarised political institutions drive the system toward crisis.
