What I've noticed about people who don't want to have kids and are older than 25 is most of them have great dedication to something else. Like they design clothes or work 24/7 in their own company or do art all the time or whatever that fills their life completely and keeps them occupied and they love it. Maybe they review games. Don't have time for children and don't really want to, they love the life they live. Opposition sees it as selfish and childish. But if you work a normal 9-5 job, are kinda bored after the first year, don't have any hobbies, it's way easier to have a kid. It gives your life meaning. You do that shitty job for the kid and you can do fun things with him/her. Opposition thinks they're above these people when they live alone in a fancy house saving money. But yeah, nothing wrong with either choice, it's cool that you can choose.
