It is time to invoke what I have called in other contexts "The Big Monkey Reverse Difference Principle."
The plutocrats are motivated in part by a desire for wealth, and in part by a desire for inequality. They want to be sure to have more wealth than others. The Reverse Difference Principle is a rule for balancing these two goals. It says that equality is to be tolerated only to the extent that it benefits the best off.
Imagine two societies. One has a great deal of inequality, but the richest 1% are relatively poor. Another society has less inequality but the richest 1% are much better than the people in the first society. Now which society to you want to be a plutocrat in?
I believe it is now the job of political philosophy to convince the plutocrats of the US this truth.
