For the first time ever people can finally choose not to have kids.
Is it really any surprise people would opt out?
Go spend a day with kids and you'll see why people would rather not deal with the mess.
Especially women who actually end up doing the majority of the work.
Add to that the extinction level pressures like climate change and the absolute lack of any benefit whatsoever in being a parent, who is crazy enough to willingly sign up for this if you actually put any thought into it instead of just "that's the way things are though!!!"
Every day I praise the man who did my vasectomy lol
My love for my daughter and my wife enrich my life and contribute more to my happiness than anything else, by far. As you wrote, the majority of the very, very hard work has fallen to my wife. I wouldn't fault any woman, or man, for not wanting it.
Still, my wife and I both feel that parenting is the best thing we've ever done or will ever do. It's everything I hoped it would be -- and much more besides. The benefits are innumerable for us.
The way I understand it, the modern sentiment is to have children meaningfully, raising them being a project parents actively invest into. Contraception brought choice, choice brought up consideration and planning. This all opened the can of "what are we doing" and "why do we do it" and "how do we do it right", that tended to be ignored in previous eras (where having or not having children was not exactly a real choice).
And for little I know about raising children is that it's one hell of a job, that requires extensive knowledge, skill, and constant heavy investment, all being an unbreakable commitment for almost two decades. Messing anything up means another human suffers the consequences. In my mind, a would-be parents have to be really competent to be confident to be able to accept the responsibility, and even then screwups are a given. Skipping on any of that, even unintentionally or from inadequate skills, means a person out there will be left to figure out how to deal with the aftermath of their upbringing. The fact a lot of people skip on all of that and just do it is no excuse.
And thus, personally, I never felt like having children. Not seriously, not after thinking about it in any depth. I messed up two cats already, messing up a human is unnecessary.
IMHO, if a society really needs new people because can't figure out how to support old ones otherwise, it should invest into professional parenting and employ people who are genuinely enthusiastic about doing that work.
1. Climate change is most certainly not an extinction level event. 2. I spend many days with kids. They are great. I suggest you do the same and experience the human experience. Someone had to deal with the piece of crap you were when you were 2 years old, after all. 3. You'll stop praising the lack of children when you are 80 and nobody young wants to take care of you. You will have a lonely, lonely existence.
