The exclusion of masses of poor from making a living by working is leading to reconsideration of the role of work in life.

In a world with too many children, taking care of them is a lot of effort — it is work. The (mainly) women who do this feel their work is undervalued, since they are either unpaid (for caring for their own children) or badly paid (when it is child-care business). The reason it is so much effort is partly due to the high birth rate and the large existing population.

If there were fewer children, so the total effort needed were much less, maybe plenty of people would be glad for the chance to play with children, show children how to do things, even take care of some children for a few hours once a week. Maybe it would be fun rather than work.
