7️⃣ 𝐑𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧𝐬: I conclude by proposing a set of recommendations to help foster this new policy paradigm, summarised in a policy matrix for researchers, policymakers, NGOs, businesses, millionaires, and citizens.

I use the concept of policy paradigm to discuss the emergence of a new way of addressing inequality in post-growth worlds. Within this paradigm, extreme wealth becomes a problem to be regulated, and income and wealth caps emerge as central policy tools.

5️⃣ 𝐏𝐮𝐛𝐥𝐢𝐜 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 𝐟𝐨𝐫 𝐦𝐚𝐱𝐢𝐦𝐮𝐦 𝐢𝐧𝐜𝐨𝐦𝐞: Chapters 3 & 4 explain how to increase public support for maximum income policies. Our experimental survey on a representative Belgian sample shows that support can reach up to 65% – when caps are set at a minimum of €500,000 combined with a 90% tax rate.

4️⃣ 𝐏𝐨𝐥𝐢𝐜𝐲 𝐝𝐞𝐬𝐢𝐠𝐧 & 𝐡𝐢𝐬𝐭𝐨𝐫𝐢𝐜𝐚𝐥 𝐜𝐚𝐬𝐞𝐬
Chapter 2 develops a framework identifying seven key parameters for designing income and wealth caps. It also analyses the political contexts in which such measures were introduced during the 20th century – and how they succeeded in reducing inequality.

Chapter 1 explains why extreme wealth is both a social and ecological issue, and how income and wealth caps can address it. I argue that these policies are transformative because they challenge the capitalist logic that underlies today’s crises.

2️⃣ 𝐀 𝐫𝐚𝐝𝐢𝐜𝐚𝐥 𝐚𝐧𝐝 𝐩𝐫𝐚𝐠𝐦𝐚𝐭𝐢𝐜 𝐫𝐞𝐬𝐞𝐚𝐫𝐜𝐡𝐞𝐫: the same chapter (section 6) outlines my epistemological stance and explains how my values and commitment to social justice led me to adopt a pragmatist inquiry – an approach aimed at generating knowledge that enables action and social change.

1️⃣ 𝐈𝐧𝐞𝐪𝐮𝐚𝐥𝐢𝐭𝐲 & 𝐩𝐨𝐬𝐭-𝐠𝐫𝐨𝐰𝐭𝐡 : in the introductory chapter (section 3), I discuss macro-economic simulations showing that reducing inequality inevitably requires reducing the wealth of the richest.
