So many economic indicators are perverse - economically it would often be better for a family to get divorced, split into two homes, and then pay each other child support. Heck, economically it would be advantageous to divorce your stay-at-home wife and turn around and hire her to take care of the kids. You could even pay her more and charge her for room and board! You could charge the kids! Financialize everything!
We need metrics that are actually tied to human happiness, not human suffering.
