David Schmidtz at Cato discusses which forms of inequality matter, i.e., which deserve intervention and redress. Replies from Peter Singer, Tom G. Palmer, and Jacob Hacker will be forthcoming. The essay is excerpted from his new book, The Elements of Justice.

The key philosophical point: that there is a prior moral question about which inequalities are ours (i.e., society’s) to arrange, lies outside the specific scope of this essay’s focus.
