I don't think there's a country in Europe that funds childcare remotely to the level of cost. The most generous I'm aware of is certain states / cities in Germany that provide free 'Kita', essentially Kindergarten. In addition to maternity leave, national insurance etc. But this certainly doesn't cover the numerous costs (including time off work etc) associated with having kids.

Would be an interesting experiment to actually pay people to have kids - i.e.: financially reward them in accordance with the costs involved. I suspect, as with an actual liveable UBI, the results would differ radically.

We do pay people to have kids in the USA - once you're on welfare. Your WIC and EBT allowances go up per kid.

And even if you're not that poor, you get subsidized kids through things like the earned income tax credit and the child tax credit. It's annoying that while some of those support 3+ kids, many "top out" at three and stop increasing.

I've often thought of searching for "sponsorships" for additional children (though we'd probably have them anyway) - not sure I want my son to be named Facebook X AI though ;)
