I like everything about the United States system except for the people running it.
Here's my plan for fixing it:
We build a Great Big Dome that looks like the sky from the inside, like on the Truman Show. And we place it over Washington DC. Then we just start a new capital someplace else, with exactly the same rules...just different people. The CIA can come, too, as long as they don't put me on some crazy list.
Meanwhile, we can let the ""statesmen in DC think they're still in power, except it would be for our entertainment instead of For Real. We can feed them fake national events and see how they respond, or send them emergency calls...we can create airplanes with tinted windows that make them think they're flying to important meetings. Of course it would all be televised. Don't worry about their wellbeing...we'd feed them and water them and change their litter boxes as needed.
