What are HN's thoughts on what happens when all populations start trending older and the use of immigrants to stop the decline runs out of steam?
Do the elderly enslave the local young populace to keep production moving?
Does the state try to incentivize the young to have children by offering state care for the new children?
Does childrearing become a function of the state?
Does the world collapse similar to the bronze age collapse and having children again becomes useful for their labor and their ability to take care of the elderly once the concept of 401ks and pensions disappear?
Thoughts? Different ideas?
