"A powerful case for limitarianism-the idea that we should set a maximum on how much resources one individual can appropriate. A must-read!" -Thomas Piketty, bestselling author of Capital in the Twenty-First Century

An original, bold, and convincing argument for a cap on wealth by the philosopher who coined the term "limitarianism."

How much money is too much? Is it ethical, and democratic, for an individual to amass a limitless amount of wealth, and then spend it however they choose? Many of us feel that the answer to that is no-but what can we do about it?

Ingrid Robeyns has long written and argued for the principle she calls "limitarianism"-or the need to limit extreme wealth. This idea is gaining momentum in the mainstream - with calls to "tax the rich" and slogans like "every billionaire is a policy failure"-but what does it mean in practice?

Robeyns explains the key reasons to support the case against extreme wealth:

It keeps the poor poor and inequalities growing It's often dirty money It undermines democracy It's one of the leading causes of climate change

Nobody actually deserves to be a millionaire There are better things to do with excess money The rich will benefit, too

This will be the first authoritative trade book to unpack the concept of a cap on wealth, where to draw the line, how to collect the excess and what to do with the money. In the process, Robeyns will ignite an urgent debate about wealth, one that calls into question the very forces we live by (capitalism and neoliberalism) and invites us to a radical reimagining of our world.
