You know what your problem is? You are using logic and rationality and simple math (I learned accounting in college).

The problem is, they dont care. The whole point is that they want control and them to be miserable. Even if you provided irrefutable proof of it, they will spend ten times more on repression than the pittance that is needed to end world hunger and poverty. It is about them feeling they are 'better' than their underlings through being a bully than actually solving problems.
