It's been like that since the Stone age. The reason it's like that is the fundamental forces that drive humans: greed, cruelty, ego and all that. Hard to expect someone in power to not get more power if he's blinded by greed. How many people do you know that voluntarily spend 25% of their income on those who are lower on the social ladder? I don't know anyone, myself included.
