Look as Israel as a cautionary tale of a country that did everything right according to the liberal prescriptions. Regardless of implementing everything that Lessig calls for, monied interests still control the political system.
How does it work?
Well, take a look at Sheldon Adelson's actions. In the US, he buys his influence by being one of the biggest GOP donors. In Israel, he buys his influence by operating the largest daily newspaper (Israel Hoyim), which he runs at a loss of 20+ million a year. Israel Hoyim is the mouthpiece of the Netanyahu government. The paper never strays from the party line, in the same way that Granma never strays from party line in Cuba. This gives Adelson a tremendous amount of influence over the government. Even moreso than he's able to buy in the US. Billionaires will always find creative ways skirt the rules and buy their influence.
