How do you afford having multiple kids?

My question is for the ones who got multiple kids in Japan. I would like to have 4-5 kids but the math simply does not work. I work in your classic traditionalshit car company and am stuck in Japanese wage system. If my wife stops working we are basically doomed.

How do you guys afford having multiple kids? How to make it work? There must be some way that I am not aware of. Thank you for your answers.
