Maybe the Norwegian model/Canadian model is a good example (not that it's increasing fertility, but it's improving affordability). We have: - Subsidized daycare - Subsidized education - 1.5 year maternity leave - Subsidies for families with children under a certain income bracket It's affordable, but couples in western countries don't really want more children (just under 2 is the average)
I was looking at how many contraceptions and items my friends bought for their newborn ranging from things related to feeding/sleeping/playing. And that's not including the highest expenses, namely shelter/transportation/food. I thought to myself, my goodness how did we ever raise children in previous millennia? Anecdotally it feels like it's becoming more and more expensive to have children. I'm fairly well-off myself, and I would probably be fine with just one child, if any.
