It is not as simple as that. In my country giving birth is free. And you get economic support for every child. For most people it's still an economic burden to some extent, but for the majority it's not something which blocks them from having children. It's more that most families I know are content with having two children. It feels fine to them. But that's the families that do have children. 25% of men in my country never have children. It's not enough. A lot of families need to produce 3 children, and better if there are some with four.. and most people simply don't want that. And that's for the most part not a question of economy.

It is as simply as that. Economic support you mentioned is never enough to cover basic needs. Better than nothing, but still require to sacrifice a lot to have an extra kid.

More kids means you need a bigger house, bigger car, extra furniture, a part time job for mother to manage kids.

I specifically mentioned families where the economy is not a burden, and they still don't want many children. Very few will want more than two. Please note that in my country at least, as long as the economy is good enough that there aren't any real problems living, then it doesn't matter if it costs more with more children. That is not the reason.

And there are the increasing infertility rates as well to hamper the efforts.

Personally, I would love to have a few kids but after many years of trying and all manner of treatments we have gotten nowhere at all. But that is just how if falls I guess.
