Fifa is a reflection of the world. All members (nations) get a vote. Most countries are corrupt. Thank go there is still a bastion of democracy/fairness left in Uefa.
The world is a reflection of the laws of physics. When complex self propagating systems coexist in an environment with limited material competition arises, and corruption is simply one inevitable result of that.
I am all in favor of a global revolution to overthrow capitalism with a solidarity of workers of the world. But I think we can have a non-corrupt FIFA without one.
Still there are plenty of world wide organizations that are less corrupt than fifa.
