I've read the first one, I can't say I disagree with your analysis but the real question is: what's to do about it? 
I don't think society can be changed. It does change by itself, it evolves, more or less at its own pace. while it evolves, how are the individual destinies ? In the past, when people felt trapped in one of the "layers" of the stack, it ended up with a bloody revolution. For as long as there's some social mobility and "hopeless ants" can strive (and sometimes succeed) to become ants, ants to become super-ants and so on, we should all be more-or-less fine. Overall, the human condition has greatly improved over the course of history. Can we do better ? Possibly. Can we do worse ? Oh yeah, that's for sure, we have already botched a couple times ! So given risk and benefit, perhaps the social stack is not great but about as good as we are able to do ...
