I think you're largely right, but there is also the fact the expectations for childrearing have significantly increased. Several generations ago children had jobs. One or two generations ago children were allowed to roam the streets until dark. Now parents have the police called on them for letting a child walk to the park alone, and are expected to curate a list of extracurricular activities they then chauffeur their child to. I'm very much not in the "it's too expensive/hard to have kids camp", but I do think we've raised the costs in many ways, at least in the US.
