There does seem to be a element of: "people who value their careers more than children end up making more money" here, which seems pretty obvious when you think about it.

From a social and corporate perspective we have a choice though: should be allow incentive systems that reward people who value their careers over their children to continue? Or should we change our incentive systems so that people who value children over career earn equal wages or even more?

Which group of people is actually more valuable to society?
