Politicians -- holders of powers that society grants only to them -- take advantage of their privileged position and outsource the rights to use their political authority on the black market of lobbies and bribes (naturally dominated by the rich). That interest group or that most powerful businessman will receive the favor of the corresponding politician.

The politicians' strategy, therefore, consists of "patrimonializing" the political authority that the population has granted them. The politician capitalizes on his authority and leases it to whoever offers the most.
