it's fairly rare for a generation (family generation) to leap from one status to a whole another level
And very difficult (new money or new blood), especially for the kids. Schemes are good, even bad ones, for without schemes you are worse off, you are lost. Do you think every society (group) would actually prefer to be a pyramid ? I think they would (because they always are).
Lobsters man, lobsters have dominance hierarchies, they ain't going away :D
Yeah, I do think a pyramid is good in a way because it gives society structure and something to start with. Just wanted to point out that it seems the older we get, the more we get entangled with it, not giving attention to more important things. : )
