"We argue that the growing income inequality over the past three decades created both a group of women who can afford to buy services that help them raise their children and run their homes, and a group who is willing to supply these services cheaply." Somehow this sentence makes me very uneasy. Rich people start having more kids because they can pay poor people to take care of them. This "everything as a service" trend of modern society is very scary because it relies heavily on income inequality, I can foresee a time in the near future where we will go back to feudal laws, a rich person will own a domain and have poor people taking care of it on their behalf.
