I agree with dead0man that the federal government is public enemy #1 at this point. Today that means breaking federal power. Tomorrow that means breaking state power. After that is breaking local power. Practically, I think it would be easiest to devolve government into oblivion.
Maybe I'm wrong & the solution is demolishing the state & local governments & then killing the federal behemoth. The historical examples of communist & fascist nations have taught me to fear centralized governments.
While I'm not nearly as right as you, I agree with your premise. It bothers me that the federal government is basically sitting on the board of most major fortune 500 companies.
