MR has this point:
the (relatively) high level of the European Gini stems from higher levels of unemployment, whereas the relatively high level of the American Gini stems from the rich being very rich.
We hear a lot about inequality, but it makes a big difference whether the inequality is the result of the rich getting richer or the poor getting poorer.
The first seems unjust, but not nearly to the degree of the later.
The real question is whether there are any privileges, and what upholds those privileges.
The church ought to be the counterbalance to all privilege, natural and political alike.
