I'm just saying that comment I replied to makes this sound as universal truth. Wanting children and being happy about having children are subjective things. There are people who don't have children and are happy about it, people who have children but are unhappy about it and everything inbetween.
People who want to have children should have them, and people who don't want to have children shoudln't have them =)
Its not a mathematical problem that you just compare the curves, some problems are hard and cannot be generalized.
And you are adding other factors if you think people who do not want kids are somehow the outliers. Same as if people wanted kids might be if you actually looked closely, for most people its not a very well thought out choice.
I'm with you wrt everything you wrote, except this part:
> People who want to have children should have them, and people who don't want to have children shoudln't have them =)
I think it's fine either way! People who want to have children are often disappointed when it's not all roses as they imagined. Conversely, people who don't want to have children are often surprised at the little joys they bring...
