Did I miss something here? Does anyone know whether these trends are unique to men? Because if (and that is a big if) this is not unique to men, that would be some horrible cherry picking / manipulative statistics.
Regardless though, the data on unmarried non-immigrant men is really disturbing. If it extends to unmarried non-immigrant women, that would harm the narrative of the article, but still present a very big problem. In general I would expect that married people have lower labour participation, because there is a partner to pick up the slack. In general, living with two people should be cheaper per person than living alone.
