Are young people overburdened by student debt to the point that it is hurting the economy? Brad Plumer of the New York Fed seems to think so. A new study has found that young adults are not making major life purchases when previous generations did and that in turn is stifling growth. Is student debt the only factor to blame or are there wider generational shifts that will have wider implications on the economy? Young people are getting married and moving to the suburbs later. The trajectory is the same, it is just happening later.
