You are so very very wrong. Everyone assumes the 'government' has a lot of power... but no one branch of the government has enough power to do shit to you. It takes their collective approach to fuck you. If the FDA didn't cooperate with the FCC and vice-versa... then marijuana promotion videos would be permitted on T.V.
My point here is, you assume that our government is big brother... The problem with your theory is that EVERYONE assumes that the government is like big brother. An even bigger problem with that is... you're looking far too hard. Plain and simple, these are all people. And while there's always going to be some form of corrupt individuals, the entire system is not corrupt.
Polls are not 'rigged'. People are not 'killed' for finding things out. The government is not planning to assassinate 3/4ths of its people. And EVEN IF the president and anyone else ATTEMPTED to do something like this... the military is not the government. I know thousands of sailors from either personal friends, friends of family, or friends of friends... Your military is not corrupt. And what happens if your government starts killing people? It ceases to exist. The military gains control, and while a military state would SUCK with restrictions, you can pretty much rest safely at night knowing men with big guns will kill anyone out after 9 pm. Lol.
As for the internet stealing and sharing info. Anything you put on their site is their property. Instead of randomly signing up for websites, try reading Terms of Service or Privacy Policy's. They're actually quite interesting.
Maybe one day America will become purely corporate. We'll run on business, and fair trade, and everything will be governed through a system of managers and adept individuals.
