“A” reason?
Given the post you’re replying to, it seems you’re implying a specific reason, but what if it’s a different one? How about “I love children but having kids is super expensive”?
Yeah, I don't envy the 30 year olds who can't buy an house because it's become unaffordable, made even harder by many only getting freelance jobs.
Also: having many children used to be an insurance policy, but as countries become more developed it's less necessary.
