It's difficult to tell exactly due to changes in technology and culture, but I'm not sure the evidence points to that. My understanding is that both the rates of home ownership and the number of middle class families where only one person works are down. It seems like a college degree is more necessary in order to get a middle class job. So if we equated college with apprenticeship I think college might result in more debt for a similar result. However, I'm not super informed about how apprenticeship worked so I could very well be mistaken.
