I don't think expanding support is really the answer. It's good, but only as good as building more hospitals because traffic accident is on the rise.
I would say a lot of it comes from unrealistic expectations, weakening of the family unit, and breakdown of community/society. It is already bad enough for milleneals like me, Gen Z will have it worse.
Seriously, if we can't figure out how to raise a kid in this new reality just yet, it better not to have children for now.
