There are many cities that seem more child friendly than others although. Like berlin, or even new york compared to SF.

Agreed. SF can afford to drive away families as long as it can continue to attract far more net population growth than the housing stock can support.

From a purely financial standpoint, skimming motivated young talent from around the world and then discouraging them from having kids or encouraging them to leave if they do seems like it would be a cheaper approach than raising a native population.
