Just to give you a flavor, here is what he writes about populist rent-seeking:
[Rent] does not contribute to growth, it only shares in what is there. Therefore, it secured by militant claims, not by productive work. It breeds populism, whose fundamental strategy is to shift responsibility for the whole to the opposite pole, the enemy. In populist discourse citizens identify with the weakest groups, regardless of their actual position in society; so they feel entitled to demand more on grounds of fairness, or even on humanitarian grounds. They do not feel responsible about production of wealth, nor about setting priorities for redistribution to the truly weak. It is others who are responsible for the big picture. Populism differs radically in this from a socialist strategy which starts from the mode of production before the mode of distribution; as well as from a political program of solidarity towards the really poor and excluded.
