The Conference Board, a business-supported research organization, has created a chart breaking down the living-at-home contingent by educational attainment. For those with a bachelor’s degree or more, the increase has been modest, from around 10% in the mid-1990s to around 13% this April. For those with less than a bachelor’s degree, the increase has been steeper, from around 15% in the mid-1990s to nearly 25% this April. The Conference Board states unequivocally: “A growing percentage of young men without a bachelor’s degree are living at home. This trend is contributing to a lower labor force participation.”... Make no mistake, though, for a young man who’s not working the couch isn’t a bed of roses. “About half of prime age men who are not in the labor force may have a serious health condition that is a barrier to working,” the late Princeton economist Alan Krueger wrote in the Brookings Papers on Economic Activity in 2017.
