I am serious about the evolutionaary psychology stuff. Those guys offer all sorts of interesting theories about how women’s brains evolved in ways that would make them want diamonds. Women take care of the children while men are freer to prowl, escape, etc. Demanding ample amounts of the man’s wealth is a smart survival strategy in that it either encourages the male to stick around or it serves as an insurance policy if he does split. But I don’t have the time to argue about the merits of sociobiology this morning.
