I've done that, but there is still corruption, so there's obviously more to it. This gets to the point that you are describing a hypothetical. If thing A were true, then this would be possible. If we all had identical values, perfect information, and unlimited time to review it, then yes many things would be possible. I don't think it is possible for the electorate to provide any more than the most superficial oversight and direction in the US Federal governmental system. It is far too big, and far too distant. And that's even if people agreed on what they wanted. 99% of people are ignorant of 99% of the activities of their elected representatives. My state has more than 5,000 bills proposed per year. Even the full time representatives don't read most of them. You say it is as simple as voting for the corruption to stop, as if that is even possible. Collective action problems are hard, as information problems. You can't just hand wave them away.
