One of the first things a woman does when a minimum of money in her pocket and a minimum of freedom is to stop giving birth. Poor people are less educated because they don’t go to school, not because they are less intelligent. Let’s leave that shit to the Americans.
The number of children per capita decreases automatically as income increases for a very simple reason. In an agricultural economy, which is a poor economy, a high number of children allows you to increase production and at the same time have a pension. The increase in productivity per capita of industrial societies eliminates this need. Not entirely. I who have no children know something about it. Although I don’t regret not having any, I must admit that it would have been practical to do so.
