1. Yes, agree, but this just depends on your opinion of what is "correct". Nature selects for survival, not correctness. I think rigid hierarchy is more advantageous for overall survival, but I am not advocating for that. I think there is something significant about the fact that humans almost always tend towards hierarchy (Lord of the Flies illustrates this).
2. I agree that large scale beauracracies are not in the best interests of humanity. I would argue for hierarchy, with less power the higher up the chain you go. E.g. Local governments should have more power than federal/national governments. But that doesn't mean there shouldn't be a national government.

I can see how one can see it that way, it is probably what those who rigging the game were thinking when they first started, and like the saying goes "those who play a rigged game gets stupid over a long period of time". That's probably why empires collapse, too much corruption and too many people playing the rigged game. A rigged game kinda corrupt workability of the whole system. The short term advantage may not be so good in the long run.
