“Capitalism also leads to birth dearth”
More precisely, having women enter the work force does. A woman who stays home raising kids does not get a salary.
Perhaps a one-child tax exemption sufficient to cause middle class women to find children more affordable would help? As a percentage of income, not a set dollar amount.
You’re right that it was women going into the workforce that did it. Basically it was the elite’s way of dropping wages by introducing twice as many people to do jobs without the corresponding increase in jobs.
France and Sweden have tried bribing women to have more kids with marginal results. There are so many things that need to be addressed to turn this around that I fear there won't be any people left for the AI robots to enslave or slaughter.
