"Being able to parent" is something you don't know about before you have your first child, and each child increases exponentially the difficulty. You can manage ok the first one and be overwhelmed when the second one is born.

Also not everyone is a trust fund kid that works at a FAANG: people get sick, lose jobs, divorce, change homes, and so on.

I'm really happy that you found the perfect antifragile optimum in your life, but this kind of "vae victis" thinking will only make parents more miserable and decrease birth rates.
