You don't around crumbs - but overwhelmingly, the culture does. You do blame women for not standing up to that culture. And as already pointed out (and not rebutted) for mammals in particular, some level of social conformity is evolutionarily adaptive. It contributes to better survival. That's why it takes intentional shifts in social mores to bring about any sort of widespread and lasting change.

And back to the nature/nurture thing, under your theory, women being held responsible for the cleanliness and appearance of their home even though other people live there is natural how...? What evolutionary (rather than social) forces brought that about, particularly considering that in Paleolithic times gatherers (and not hunters) contributed most of the food to the tribe on any given day?
