"In the United States, the fundamental cause of corruption in the political system is voters. (So well demonstrated in “What’s the matter with Kansas?”)

And ignorance and irrational decision making are the main problems."

Those pesky voters!  If only there was a system where the enlightened elites such as yourself could require everyone to do precisely as you say instead of insisting on ignoring your omniscience!

Alas!  So much ignorance and irrationality when there are those who have all the answers and just need the power to implement the solutions.
