That is known to exist indeed, countries in which most people can simply live off social money, like Sweden, have better birth rates. But, all of those countries are below replacement level anyway... There is no way for a rich country to be above replacement level this days. Their success varies, but it all seems like that being rich is incompatible with having kids. Even in single countries, for which statistics like that is available, birth rates are higher in poorer income groups, like it is in USA. Households making over $200K have 1.5x fewer kids than the poorest households. Both between countries, and within countries, main drivers of reproduction are poverty and low educational attainment.
