If you want to do deep data analysis, it helps that the OECD collects a lot of data from Japan, South Korea, the US, and the member countries which are all generally developed. I just don't think, that if it is a factor, that it has much impact, given that the worst countries do not have this factor; the child(ren) is still pretty much the extent of the social safety net. Japan is also notable in that they actually give significantly lower social security payments to women, especially unmarried or divorcees.
