Battling corruption is something that never stops the second people go to sleep it continues unabated. Its not a war you can win, its an endless battle.

Democracy is first about making demands and unless we want somebody telling politicians our needs on behalf of us (almost always a corporation or the wealthy trying to do this) just voting and then going to sleep is a recipe for corruption. Its how we got here.

You have to elect politicians AND make demands of them, else the squeaky billionaire gets the grease.
