Then by all means, define a better layout for organization. To be clear, I am not advocating that we should have people who are mentally unsound in positions of power, or that our current system is in any way 'correct' (or even good) but it is the logical outcome of the growth of the system. We can observe this as it happens repeatedly in recorded history.
While the last century of that growth has clearly been manipulated (from inside, by its own selection pressures), all of it is very much an organic outgrowth of the basic need for organization. Further, we are able, through our own records, to observe that there is a clear pattern, and that pattern happens no matter how we seek to organize.
Historically the only recourse to corrupt power structures is to pull them down and start over, then, in right around two hundred years, do it again.
I can envision no method of organization that does not have the same weaknesses in its structure that every preceding one has. So it is very likely that it is not possible for a human mind to adequately conceptualize the system we would require to avoid the problems you are concerned with without utilizing the same method of iteration that we have been using for around ten thousand years now. Because one thing we definitely are not, is capable of the level of long-term planning that would allow us to overcome the weaknesses of our systems.
Edit: Now, that probably comes off as a bit more confrontational than it is intended, sorry about that. What I'm trying to say is that there do not appear to be an reasonable alternatives available to any of humanity at this point in time, ad I would actually be interested in seeing if anyone has some workable ideas, because I have nothing, and as far as I can tell, there aren't any functional options in any discussions anywhere.
