Political power is one form of power; political action are one kind of action. The point I made encompassed them. For example "the ability to be heard" increases with wealth: having your opinion be prominent in a democratic society is politically powerful and the more money you have the more you are able to finance outlets for your views.

One's ability to make money - to have one's skills suit the market; or to be lucky - has nothing to do with the value of your opinions or how frequently/prominently they should be offered to the rest of us.

pg doesn't even begin to engage in anything like this critique of inequality. I dont really think he knows anything about why serious academic researchers and writers have seen inequality as a serious problem for democractic societies. Because he hasnt spent the time to find out.
