Having kids is such a traumatic, life-changing event. I mean this in the most positive way. I can see why so many people see this as the before/after watershed moment of their lives and ambitions. However, it's understandable that not everyone needs to have kids to come to this realization.
For me it was the profound perspective shift from being a leaf node of a tree so to speak to becoming just one link in a long chain. It tends to relax the do-or-die drive quite a bit.
It also makes it feel all the more exploitative that young developers are encouraged to work long hours and put their everything into their job. And that women are de-incentivized to have children by the market, if not capitalist society at large - don't do it, it'll cost you your career! We only give you two weeks of leave after you gave birth. You can't afford child care, or all your wages would be spent on it! etc.
It’s not, really. Japan is absurdly good if the only thing you want to do is have children, and don’t care too much about how or where they’re schooled.
1 year of leave per child, inability to get fired while on leave, free childcare.
The only negative is that all those make advancement options for working age women 25-35 whom are expected to have kids ’soon’ nonexistent.
