The Economist has a new editor-in-chief, Zanny Minton Beddoes. (http://www.economist.com/mediadirectory/zanny-minton-beddoes)
She got the job in January of this year. Since then she's made some big changes to the editorial stance of the paper (magazine, whatever) - all vastly for the better, in my opinion. This is the latest result.
(The editor-in-chief approves the opinion pieces at the front of the magazine.)
I'm really happy with her - she's right on a lot of things.
Lessig has done a lot of good things, and I admire his idealism and dedication.
But money in politics is there because politicians have the power to choose winners and losers, to rig markets, to implement regulations that protect incumbents, to choose who is taxed and who isn't, etc., etc., etc.
As long as politicians have those powers (as opposed to the far more limited powers intended by the founders), those with power and wealth will find ways to influence politicians - one way or another.
No law can prevent that - laws can only force the influence under the table, underground where it can't be seen.
Money in politics is the symptom. Too much power in the hands of politicians is the disease.
