>Such expectations are utterly selfish<
No, Julie, abandoning YOUR children, so you can have more spending money is "utterly selfish".
What makes you imagine Julie having children? As any 20-year-old sociology major can tell you: "Diapers are so, wellllll, yucky!!!! Especially compared to being a partisan of Ugo Chavez and Che!!!!!!! And to pushing poor people around with an unearned air of social and even pseudo-intellectual superiority."
