The failure of the Occupy movement has been that it is primarily been driven at an emotional level, and (if my own experiences have shown anything) has lacked serious thought.
So, here, we're all designers/engineers/entrepeneurs, let's talk about this.
Goal:
Fix what is broken with the US federal government.
Constraints:
Any proposed solution cannot disrupt current economy significantly (avoid riots, breaking public services, hurting people. etc.).
Any proposed solution must be straightforward in implementation and simple in explanation (average Joes and Janes need to be able to get it--no GNU cat() implmentations, please).
Any proposed solution must gracefully integrate or deprecate existing systems where possible (see defense, messaging [postal service], FCC, IRS, etc.)--this need not include existing legislative organs, however (those are command mechanisms, which probably would need to be replaced wholesale anyways).
Any proposed solution must allow active participation by the governed and allow for expression of their will. This implies any solution must allow for equal, open, and easy access to the functioning of the government.
Suggested starting point:
1. Identify what is actually wrong with the government.
EDIT: Updated example list of existing systems example. Added constraint for "expression of governed's will".
