Ludwig von Mises

This is one of the two fundamental weaknesses of all parties aiming at privileges on behalf of special interests. On the one hand, they are obliged to rely on only a small group, because privileges cease to be privileges when they are granted to the majority; but, on the other hand, it is only in their guise as the champions and representatives of the majority that they have any prospect of realizing their demands.

Ludwig von Mises, Liberalism, first published in German as Liberalismus, 1927, and in English as The Free and Prosperous Commonwealth, 1962.
