There are definitely people who WANT kids, like another commenter in this chain describes. I don’t get the impression MOST people are like that though. Anyone who suspects they might have regrets or will be giving things up... I don’t know if they should go through with it.
That's where we're at. We're open to changing our minds depending on our situation, which is about as good as we could hope for (not rich but relatively secure and very happy). Since things are good and we feel fulfilled, it's hard to justify significant compromises. We're really clear that if either of us changes our mind, we'll talk about it, and we check in with each other from time to time just to make sure, but we already have more interests than we have time to properly nurture.
You shouldn't feel any guilt about existing, though.
Not to say having kids is ever super easy but there are definitely people that live a pretty kid friendly lifestyle without them.
It's important to keep this in mind because we do tend to place weight on others deciding to do something. It's why companies like to slap their logo on everything. If my friends were jumping off a bridge I absolutely would consider following them. I like to think one would stop to briefly inform me of whatever horror they're running from but absent that yeah I'd be pretty tempted to follow suit.
So we see all of these people having kids and think "the sacrifice must be worth it" but so many of those people would have been working standards 9-5's and pairing up to go live in the same suburb for the rest of their life where they'll wear clothes in the house and barely even walk each other on leashes anyway. They didn't have to give up their hobbies and dreams. If you do, you're facing a different equation than they did.
