Sorry but I have to pick a bone with you about one of your contentions: having children is a choice. Are you contributing to society? At a basic level of course if no one had children we'd cease to exist but at the same time it's also arguable that there are simply too many of us on the planet to support, which shifts having children into a more selfish choice.
On a more personal level, I suspect you chose to had kids because you wanted kids. This is fine. But you're not doing this for the good of society.
Lastly, in the developed world we WAY overspend on child-rearing. Like... it's ridiculous. It may well be that in the US each child will cost nigh on $1m to raise. That's... ludicrous. But it also comes about from making a bunch of unessential choices (eg private school). Again, if that's what you want to do, fine. But it's another choice.
