Re-election every couple of years does not solve the issues, as demonstrated by most elected governments around the world. People are too lazy, uninformed, stupid, to vote for their own good, and will be made to vote against their own interest, time and time again. As societies we are mostly not ready mentally to vote properly. This is in the interest of the people in power. Have stupid and confused subjects, so that you can rally them for whatever cause you need them to rally for.
