The Problem is the System

Jorge Chabat says that Mexico's network of regulations and norms are to blame for the nation's dysfunctional politics, not the politicians themselves:

The political system that we have is an inheritence from that which the PRI constructed to maintain its hegemony. To reach this objective the "super party" eliminated the possibility of immediate reelection so that deputies, senators, mayors, and governors couldn't develop a power base independent from the party. This design has now benefitted all of the parties, which feel very comfortable with this priísta contribution to the disaster we now have. The other key to the political system was the impunity and the selectivity in the application of laws. In fact, to make a political career it was necessary to join this scheme whether through action or omission. In this sense all the politicians were hostage to a system because everyone had a piece of skin exposed. The figure of the fuero [the special legal exemption reserved for Mexican politicians], which functions as a blanket immunity for politicians to do whatever they want, has its origins in that system. 

So the origin of the incredible inefficiency, irresponsibility, and corruption of our politicians is in the system that we have that incentivizes that type of conduct. The solution, then, is in changing the rules of the game, not the players. That's why all the social discontent must concentrate on concrete demands that break with this perverse model of practicing politics, beginning with the rule that prohibits immediate reelection. Only in this way will we be able to channel the energy of the citizens that until now, just like heat, disperses in the universe without producing any change.
