Someone has to bring up the next generation, the no kids crowd want all the luxury of having the next generation without putting in the effort or spending the money.
Instead, people who like having kids should have more kids. This would proliferate a healthy culture that sees kids as a source of happiness, not a burden of misery taken out of necessity.
To make this work you need some kind of cross-subsidy (e.g. large child tax credit), because having a larger number of kids requires the means as well as the will and the people willing to do it aren't all billionaires.
But then we do essentially the opposite and drive up housing prices when larger families need more house. Higher housing prices are essentially a transfer from young and future families to retirees.
I would describe myself as being the converse of that statement. I do not believe my desires should truly have much of a bearing on my situation.
The assumption that humanity must, and shall, exist forever has no proof.
I grew up with emotional neglect and all sorts of mental health struggles that grew from that, so I find the cavalier attitude people have towards parenting and how people in the world treat each other in general appalling.
My parents (and honestly most, in my opinion) were not qualified to be parents. They were deeply broken themselves and didn't even have awareness of that.
I know humans could do better, but looking at the state of things, greed and hatred and aggression in all forms from interpersonal to wars are propagating themselves as the most successful traits. In a dog eat dog world, I'd much rather leave everything to animals, at least they don't destroy the entire planet when they maul each other
Who do you think pays for schools-kindergartens for your kids while you getting tax credits for them and likely for your dependent wife who doesn't work while rearing them? And on top of that for your kid's healthcare in many European countries...
In my opinion, it's better to not have kids when you are not 100% LOCKED IN on wanting them instead of gambling and potentially being forced into a commitment you never wanted to make.
Almost all the teachers I know have kids. Most scientists do. Einstein had three kids, Dirac four, and Planck five. Marie and Pierre Curie managed two.
