These also hold for single, childless men and women. But that's almost besides the point: you can just as well say that men work more hours because society demands they sacrifice their well-being to earn more income.

The only reason your formulation gets more play in media is that there's a strong social bias ascribing hypoagency to women (so whatever unfair pressures they face are due to patriarchal oppression) and hyperagency to men (so whatever unfair pressures they face are their own fault).
