"His research suggests that men aged 21 to 30 without a college degree worked 12 percent less in 2015 than they did in 2000, and men aged 31 to 55 worked 8 percent less. Women’s shares were lower: younger women worked 7 percent less, while older women worked four percent less. Much of this decline is not just that all men worked fewer hours, but that a large number of men just stopped working, Hurst said, a trend that he attributed to automation and the disappearance of good jobs. The fraction of men who say they had worked zero hours over the past year has skyrocketed since 2000, he found. As they drop out of the labor force, men depend on family members and partners more, in some cases quite a lot. About 70 percent of non-working men ages 21 to 30 live with a parent or close relative other than a spouse, according to the Hurst data; 20 percent live with a spouse or with friends."
