I think not having kids is a life choice anyone will regret as they get older.
Here's my thought on this.
I actually don't mind (CARE is a better word) If somebody decides not to have kids. But I do think people will regret it at a certain point. However, what I find horrible is how people lie to themselves when giving reasons on why not to have kids. Saying stuff like "world is already overpopulated" "people are destroying the planet" (TV Show Utopia is great, though), "I don't want to raise a kid in THIS world", etc. Such things are fucking bullshit. World nowadays has shitload of flaws, that's for sure, but compared to the past it's still quite great, no, since parents used to lose like 4 out of 5-6 kids in the past as just one example. Secondly, I find it silly how some certain people put themselves in a role of God, worrying about planets resources LOL, I mean c'mon give me a break. There's a handful of people marrying older women who can't have kids so they have to give some sort of reason to lie to themselves since it's brutal to say it's because of their age imo. As for a financial standpoint, I don't want to comment on it as people from the West live entirely different life compared to me, so their expense is something that I never had myself most likely, so I don't even know the feel of missing out, but still, it's not like I'm crying over some things that I can't have. We're just mere mortals. I don't know why some folks give themsevles an idea of knowing how the world is going to be. What if world doesn't end in a war and we don't die, what if AI doesn't destroy us all? What if in 15 years it turns out that life just continues, like it used to continue until now? It's easier for men. But it's women that won't be able to get pregnant and we won't be able to get that time back. The "mistake" of that is unmeasurable imo.
Life is great. Literally great. Imo it's quite selfish not to give it someone else, but rather enjoy it yourself. Spend your money on what? Cars? Houses? Travels? Food? Sure, it's all cool and great, but on a bigger scale it's a dogshit and can't come even close to a family.
