When will American citizens get tired of the corrupt government and begin a new revolution?

We all know the politicians in DC are corrupt and only looking out for themselves. We know the government is complicit in many of the atrocities around the world, either directly or in the use of "foreign aid". Saddam Hussein and Osama bin Laden were previously tools of the CIA, who gave them advanced training and weapons in the past. We're all tired of seeing money being loaned to other countries that never pay it back, and knowing that money could be used to make America better. When will we say we've had enough? When will we take back our government and make it work for the citizens of this country?
