I don’t think there is enough talk about this. You think the 08 housing bubble was bad? Wait until the housing market crashes when all of the traditional middle class is unable to afford home-ownership because they are strapped under the weight of student loans. This student loan debt bubble is going to have serious ramifications as time goes on and we haven’t even gotten close to the peak yet.
