Yeah, I don't agree with the guy you're answering. I know plenty of great people who just don't want kids and don't find time with them to be rewarding or gratifying, and there's nothing wrong with that. Having kids most definitely doesn't guarantee that old age will be any better either. Even if it did, it's not worth decades of labor and costs that you don't want. Saving for retirement/end of life care is much easier when you don't have kids, too. If you don't want kids, more power to you.
