Birthrate isn't my point. Per your chart birth rates are down for everyone. The fact remains that poor people have more children. And more to the original point, people aren't being forced to leave their children.

My point is lack of access to contraceptives and lack of women’s financial independence might be the reason poorer women have more children. My conjecture is their higher birth rates have little to do with them being poorer.

Sure, but that has nothing to do with the original comment which is to say that women don't have to go to work. Nor do men.

I am "poor" by choice because my wife takes care of the children in our household. Our lives are richer than those of countless lonely $ millionaires.

This is the real answer. Nothing else is going to change that. A basic lifestyle isn't that expensive and it's exponentially better than 99% of people's lives 50 years ago. Just making smart shopping decisions can literally double or more your buying power.

I really don't get the point of doing something you don't enjoy for 8-12 hours a day just so you can have expensive things.

Not quite. $ rich people can't afford time with children.
