Parenting is a nonmarket activity; so much sacrifice and service goes into it without any assurance that the providers will get anything back. Mercy, justice; they are nonmarket. Care, service; nonmarket. Solidarity, fidelity; nonmarket. Sweetness and kindness and gentleness. All nonmarket.
It is hard for people to do good for the simple act of doing good. These days, most people want something back in return and therefore it is hard to see change and good in this world without a price to pay. I have been told that there is no such thing as a free lunch and in the end we pay for everything somehow. It is sad that this is how we have become as a country and world even know.
