We have elections because they are meaningless. Show me one country where there is a party that actually has a chance to become part of a government that would change the status quo.
Show me a single democratic country where the voters agree which way the status quo should be changed. It seems to me that status quo rarely changes a lot in a single election because it already reflects a decent compromise between the interests of various people, organizations and ideals that make up a nation.
It's not the mirror's fault that what it reveals leaves a lot to be desired.
