Incentivising to have more kids is not going to work. Things have changed. A lot of people just don't want to have children, and it isn't a financial issue.
There does not seem to be a strong correlation between countries which make it easier and more affordable to have children, and the replacement rate.
The government isn't just responsible for finance but all of society. Incentivizing kids doesn't have to just mean dangling money in front of parents. Not having government-funded media encourage lifestyles that lead to less children would be a good start.
Hopeless measures. Nothing can persuade a couple to f... for kids, except if you force a medieval-like state based on religion and women oppression. Only such states historically guarantee >2 kids per couple, unfortunately.
If a progressive state can only exist as long as somewhere else oppressed woman keep supplying human material then it's not that progressive after all.
Long term: incentivize to have more kids.
this will solve the problem in ~25 - 30 years.
but that's too late for most voters and politicians today...
there should be a term for that? how about democracies demographics dilemma?
