When did we accept that the only way to use our time is to maximize the remuneration for it?

To pass off child care just because “I can make more working,” or to have someone mow because, “I could make more elsewhere” denies that a well-rounded expertise is valuable in itself, or that your participation with an activity brings value to it. Maximization of returns at the cost of all else is a neoclassical economist’s wet dream that has slithered its way into the common sense of every home.
