I want to point out that you assumed FWAUs are generally moving toward a lower entropy state; I don't think MBT says anything of that nature.
Yes, I’m not sure I remember the book stating this; however, I have concluded it from my own observations. The vast, overwhelming majority of people I interact with on a daily basis sincerely intend to (and do) improve themselves and extend love to their circle of friends and family and beyond. Only very seldom do I encounter a sociopath out for the destruction of relationships. Furthermore, I have also observed many cases of entropy-reduction during a single lifetime of individuals. A youth of crime and crudity to a middle-age of contributions and civility. A person learning that greed and power are not the solutions to unhappiness. Yes, I know they are probably just "catching up" to their previously achieved quality, but nonetheless it is evidence that the system works. So I think it is safe to say that this PMR “works,” i.e. it provides conditions in which the entropy of IUOCs is for the most part consistently lowering.
So I guess what I am wondering is, is there such a phenomenon as "human society," is that system evolving, and does that system work, i.e. is it a system that supports the evolution of consciousness? AUM is an evolving system, PMR is an evolving system--they self-modify into more profitable configurations. To me, human social institutions are likewise evolving systems, human society is also an evolving system, and they are, on average, evolving in the right direction.
Lumpy you may be right that it is impossible to tell from subjective viewpoints, but doesn't it seem to you that life is less brutish, nasty, and short for a good proportion of the planet? Especially when compared to the past? And much of that is owing to the systems we have devised to take care of each other.
What is evidenced within society is only a reflection of the qualities of the members of that society.
I think that because our social institutions have evolved in a lower entropy direction, that indicates to me that there are proportionally higher quality consciousness units interacting in this PMR than there were 3000 years ago.
Therefore I am beginning to think that this is not forever destined to be a kindergarten, but it is possible that someday human society will evolve into a high school. If we have better organized (more profitable) social institutions, why would we continue to receive tons of low quality consciousness? It would be like putting a kindergartner in a higher grade--they wouldn't get much out of it and it would be annoying for the older kids.
