I do think that there will always be a hierarchy, just because many people aspire to power and are competitive, while others are not so bent on leadership and status. However, it's the NASTINESS that I find completely unwarranted, and even antithetical (is that the right word?) to the idea of what authority should be. Why would one want to lead if one had nothing but contempt and spite towards one's followers? Power over others for power's own sake is useless - there should be something one actually wants to DO with it for (at very least what they believe to be) the better.
The other thing I think to be useless is the belief that because someone is in a position of authority or higher up in society, they are necessarily right, which is what many leaders and followers alike will try to tell you. It should - no, it has to be - the other way around, that someone must be right, and do right, or at least attempt it, in order to maintain their power, and the best way to prove it is to allow discussions and suggestions, and yes, criticism. I have no respect for authorities that have no merit and questionable intentions, who have only their positions and the arbitrary qualities that got them to that point by which to prove themselves, and I will not stop from questioning and opposing them, even, if I don't think they're right. If authority is bad authority, then anything less than that is doing a disservice to myself and others, not getting the best we can expect from someone who claims to know and do better than ourselves. A bad hierarchy that refuses to reform itself does not deserve to exist.
....Probably got a bit off topic there, pushing this more into the realm of the PPR forum, but I still think it's rather relevant.
