From investors and monetary authorities to governments and policy makers, almost everyone had assumed inflation was dead and buried. But now people the world over are confronting a poisonous new economic reality and, with it, the prospect of vast and increasing wealth inequality. How have we arrived in this situation?

We Need to Talk About Inflation cuts through centuries of bad judgment and misunderstanding, offering a means to intervene now—so we can begin to tackle the political and social upheaval unleashed by inflation.
