I agree with that statement. The question now is "what is the solution for corruption?" Human nature is selfish, which leads someone with power and authority to abuse it for their own personal gain. The solution lies in providing the most reward to people with the authority when they make the "ethical" decision. *I quote "ethical" because it's never as simple as A is ethical, B is not. I use ethical as meaning not corrupt - which also needs a better definition.
