Excerpt: An unpublished paper by Mark Aguiar at Princeton University and three co-authors suggests another potential obstacle: that better video games could be luring young men away from work. Mr Krueger reports that among men aged 21-30 “idleness”—meaning not working, seeking work or studying—rose by 3.5 percentage points between 1994 and 2014. Over the past eight or so years, the time young men outside the labour force spent gaming rose from 3.6 to 6.7 hours per week.
