It’s not that simple. Birth rates are also down in European countries where having a child is not a significant financial burden.
Here’s an interesting recent interview on the topic with a leading Finnish demographer:

Twenty years ago, Finland appeared to have it all. The birth rate was rising and the proportion of women in the labour force was high. Policymakers from around the world, including the UK and east Asia, came to learn about the Nordic model behind it: world class maternity care; generous parental leave; a right to pre-school childcare.
But maybe they got it wrong. Despite all the support offered to parents, Finland’s fertility rate has fallen nearly a third since 2010. It is now below the UK’s, where the social safety net is more limited, and only slightly above Italy’s, where traditional gender roles persevere.
“The strange thing with fertility is nobody really knows what’s going on. The policy responses are untried because it’s a new situation. It’s not primarily driven by economics or family policies. It’s something cultural, psychological, biological, cognitive.”
At the Family Federation, Rotkirch oversees a unique series of surveys, which ask young people not just how many children they are planning to have, but how many they would ideally like to have.
Her findings suggest that children do not fit into many millennials’ life plans. Once it was a sacrifice not to have children; now starting a family means sacrificing independence. “In most societies, having children was a cornerstone of adulthood. Now it’s something you have if you already have everything else. It becomes the capstone.”
