I think that most of western Europe is fucked in that sense. Previous generations piled up a ton of debt and so now there is no breathing room for subsidize affordable housing, parenting benefits, ... . Add to that that you need 2 salaries to live, that you must study until when you are 25+ to have a degree, that you don't want to have a baby just when you career is starting, that housing is extremely expensive, that you need to save for your pension because clearly the pension system will be drastically neutered in the future due to the above mentioned debt, ... . Basically, there are a bunch of factors that stop many many couples from having children.

I'm Italian so the situations is similar if not worse back at home.
