No thats obviously the executive?

Yes this is how democracy works, if people are dumb, then things go bad. The point of democracy is that you have to take a leap of faith and hope people make good decisions. If you don't like this, we can just revert to totalitarianism. You might think I'm saying this tongue in cheek but I'm not, there's a real argument that modernity is too complex for democracy.
