Let's suppose it is so. But what to do about it? Accept as the way of Nature? Purge the weak? Make them strong or die trying? Let them be governed by the strong, for only they can be good leaders? Diagnosis is only the first step on the road to health.
Well, I'm not a fan of purging, as crushing those whom you can simply because you can is the greatest proof of weakness. The vast majority of conflict is caused by weaklings trying to prove they're not weak.
