Frankly, the only reason BIG is not adopted by the power centers is that they do not (yet) understand how well it serves their purpose. So proponents should maybe change their strategy: In addition to explaining to the sheeple how they get goodies, they should explain to really powerful people like Cheney, Haass and Schäuble how BIG can be used to centralize power.
How would a well balanced BIG empower the government? It would simplify so much and make the government much leaner.
