Hi, thanks for the post. I don't know what your personal circumstances are, where you live, how mobile your job and your wife's job are, but: have you considered working remotely and then moving to somewhere that your salary would go further, and thus give you more time to be with your kids?
For example: if you managed to get a remote job making $50,000 USD a year, that's a pretty good living for a family in a small city in Spain, France, Italy, Poland, Czechia, the Balkans, etc. You could work less hours (and have no commute) and your wife might not even have to work at all. Or you could both work part-time.
As I said, it's not as easy as I make it sound, but it's something to consider.
