What, if Anything, is Wrong with Extreme Wealth?

This paper proposes a view, called limitarianism, which suggests that there should be upper limits to the amount of income and wealth a person can hold. One argument for limitarianism is that superriches can undermine political equality. The other reason is that it would be better if the surplus money that superrich households have were to be used to meet unmet urgent needs and local and global collective action problems. A particular urgent case of the latter is climate change. The paper discusses one objection to limitarianism, and draws some conclusions for society, as well as for the human development paradigm and the capability approach.
