There are three distinct forces that conspire to produce a great deal of economic misery. We can refer to them, for convenience, as misfortune, unfairness, and improvidence. Political philosophers have often shown an interest in one or another of these, but seldom all three. Furthermore, those who do acknowledge all three have often felt driven to collapse them into one root cause of inequality. My goal in this essay will be to argue that the three are independent of one another, but more importantly, that they each require distinct remedies. This is important for egalitarians because it defeats any attempt to develop a “one-size-fits-all” policy aimed at creating a more equal society. This analysis helps us to understand several of the tensions that arise in our attempts to combat inequality that are often obscured by an overemphasis on the power of redistributive taxation as well as generalized inattention to the way that successful welfare states achieve meaningful progress in promoting greater equality.

The distributive justice literature has recently formulated several tax proposals, with limitarians or property-owning democrats proposing new or higher taxes on wealth or capital income intended to decrease the growing wealth gap. This essay joins this debate on inequality and redistributive taxation through the lens of the “benefit principle for public policy.” This principle says that specific rules and institutions are acceptable to the extent that they create benefits for all individuals in society, or at least don’t make anyone worse off. This benefit principle opposes wealth accumulation to the extent that wealth was generated through rent-seeking—that is, income unrelated to economic productivity, which is not embedded in mutually beneficial exchanges. I maintain, however, that ruling out rent-seeking requires not ex post taxation, but primarily a more “predistributive corrective policy,” that is, reconfiguration of market institutions to prevent wealth accumulation through rent-seeking in the first place. The alternative response is, thus, not to tackle inequality as such but to reform the market to promote the occurrence of mutually beneficial exchange.
