Put simply, a poor person has not been allocated the stuff (or the ability to buy it) that a rich person has. The needs of the rich and poor are met and unmet in wildly different ways: the potential to fully articulate their humanity is cut off at the root for some, while others are granted space to flourish. Inequality limits what a person, and indeed society, could otherwise do; it delimits our freedom. Past generations have fought to expand the realm of freedom—to ensure all adult humans have the same rights and to ensure that any new capabilities delivered through technological advance are to be made available to all. And if we are to continue this battle to correct the titanic, manifest unfairness of the way things are, we must therefore wage a struggle over which method for the allocation of things we want as a society.
