Any attempt at listing all the sources of criminality, corruption and pure evil in our US system inevitably leads one to the conclusion that the evil ones are far too intertwined and widespread in our system for there ever to be a simple purge of the bad elements. Simply leaving the basic structure of the government intact, leaving some branch of government intact will not work.
The entire system needs to be demolished, removing everyone in power, for there ever to be any honesty and/or sanity put into our government.
Is this likely to happen? No freakin' way.
Is it possible?
Yes-- if enough people wake up and act.
