I would correct that to *chasing the top can be rational under certain assumptions. The worse the inequality gets in society, the more rational it is to chase the top, in fact - specifically for women. As I wrote in another comment, it can be better to be the Nth wife of a prince rather than the first wife of a commoner (if you're optimizing for the survival/fitness of your offspring, albeit unconsciously).
