I think it is not only issue with the price but also with the time to prepare it. They do not survive using one salary to have more time to care of the children. Or lets say two salaries but 1/2 work time both.

Actually, there is no place on earth nowadays to have possibility like that, with one salary.

And people are wondering why young generations do not make children.

Gen Silent with one salary had 5 boomer children. I would love to have one salary and 2.5 children working half time

Or move to really small country like Luxembourg, Malta, Andora and be a country representative player

why no one create a third one? is it blocked somehow?

I guess TLTR summary could be added here
