The pros/cons seem stacked because they are. This is coming from my perspective of someone who has chosen not to have children, but has friends who have.
It's not something you can really pro/con to make the "right" choice. You have to want to do it in spite of it changing your relationship, your body, your lifestyle, your everything. In some ways better, some worse. Some changes will evolve or ebb and flow with the seasons of life, and some will just be permanent.
I know that I can't handle all that uncertainty, all that change. And while I also never really had the desire to raise and shape a child, as I've gotten older I've realized that I get to have those moments. In doses I can handle and without sacrifices, because they are not my kids. I'm an auntie (biological and chosen). I have plenty of friends with kids (and plenty without). I feel like I get the best of both worlds.
Imagine your life in both scenarios. What brings you the most joy?
The target needs to be capitalism. Not Walmart, not Target, not Amazon. Just quitting the sheer amount of shit we buy that is not necessary. Reassessing our understanding of the word necessary. And for the things that are truly necessary, buying from companies who don't race to the bottom with the most low-quality instant garbage they want to break so we'll but another one.
I'm not talking about boycotting shitty companies, though. Just like, boycotting capitalism. To the degree that's even possible. We need food, shelter, and utilities.
But clothes? Repair, swap, thrift.
Entertainment? Cancel streaming services, stop going out to movies. Don't use social media sites that make money by showing you ads. Play cards or board games, read or listen to books from the library. Trade things with friends when you get bored of what you have instead of just buying new stuff. Touch grass.
I'm not saying I do all of this stuff or that it would be easy, but lots of people doing this consistently would make a much bigger difference than boycotting shitty companies piecemeal.
Opting out of consumerism. Not that it's legal disobedience, but it's certainly social disobedience that would get the attention of and take power from the corporations who control our politicians. Yes we can't stop buying everything completely, going to a barter system for everything is not feasible. But we can at least stop buying so much crap.
Yeah, I was thinking the 30 from your original post is rookie numbers.
