Is the concern that we'd marginalize parents and kids? As a parent of little kids, that's a concern that wasn't even on my radar. I had no idea that that was a major concern of people. Wild. I'm not saying it is a fabricated or unfounded fear, I just don't have that concern at all for myself.

As a parent of little kids, I worry much more about them living fulfilling lives as they grow up in the future. I'm concerned about climate change, wars, and an economic system that will allow them to live self-actualized lives. I have no doubt that the population number plays some factor in that, creating problems that must be solved. But ultimately, humans have created amazing technologies and the Earth is bountiful. We can support whatever number of people is on the horizon (whether that number is larger or smaller), but society must choose to do so and adapt.

My greatest fears are that governments and corporations consolidate their wealth and power to only an elite few, bending society to serve that elite. That is a fear exists regardless of the fertility rate.

I think Charlie Chaplin's speech at the end of The Great Dictator is relevant and inspirational: https://www.youtube.com/watch?v=J7GY1Xg6X20&t=2s

Thank you for sharing your article. It's from a view so unlike my own, and it's been eye opening.

The concern is that if the birthrate drops low enough that having kids becomes unusual, it causes societal changes that create a negative feedback loop that will continue pushing the birthrate lower and lower. If the number of elderly far exceeds the number of working people (which is already locked in for South Korea), you then have to figure out how to restructure society around this while maintaining social order.
