That would be great, but I never heard any realistic proposals how to make educated women with good opportunities want to birth and rear 3+ children.
Countries like Sweden and Norway have equal non-transferable paternity leaves and "free" daycare/education/healthcare. They birth rates are still nowhere near replacement levels. The hard truth seems to be that majority of women with education and opportunities don't want to spend their best years on children and bear the cost to their health from multiple child births.

Please. Now is objectively the best, safest time to have children. When western societies had high birth rates the expectation was basically "it is a coin toss whether a child will survive until adulthood and then they will have to deal with wars, famines and epidemics".
This argument is rather one dimensional. If you're trying to solve the problem in modern developed society, you can't look to what happens at a more primal level, you need to address the actual concerns people are living with.
We have more choice and visibility into options and unfair power structures now, and unless your solution is to remove choice again, then looking back to a time when people depended on children for survival and safety isn't going to offer much relevant insight. Instead it's going to lock you into positions with no way out.
Personally I am of the opinion that everyone is entitled to their own life, and that the default assumption should be that they make conscious decisions in line with their own preferences.
Have a child? Great, but don't complain to me about early mornings and stress... you knew that before you had one. No child? Go for it! But don't complain to me about loneliness and lack of purpose.
I'm leaning towards the no child camp myself. I love my long morning, and complete lack of some little createurs (rightful) demand on my time. Yes, I won't have the pleasure of seeing that little creature grow up, and I might have a lonelier old age (but there's plenty of social settings I can inject myself into), but that's life. There's advantages and disadvantages to everything.
The trick is to find out which ones you like more.
