> You cant have a robust welfare state and make through policy and propaganda 4+ child families rare.

I'm curios what do you mean by this. Could you provide some examples of such policies or propaganda campaigns?

Legalizing abortion, unneeded regulations that require car seats at later ages which disincentivize more children for lack of car space, zoning that removes green space and side walks in favor of car infrastructure, expensive education and health insurance (family premiums are insane compared to individual), incentivizing two worker house holds through tax policy.

Health insurance? Are you sure you are talking about welfare states and not America? Which welfare state has expensive education and health insurances?
