I don't understand why you would find it confusing for the 'elites' to screw up when trying to run governments or otherwise improve the world. Human motivation is the same at any level on the power curve or on the intelligence curve. Those people screw up at improving the world because the goals they're trying to attain is greater wealth, power, and influence for themselves. If those at the top concerned themselves with improving the lot of people at the bottom, maybe they would succeed at it. However, unless they actually make the effort (human nature being what it is, this will never happen), nothing will change.
