There’s a simple, visceral reason for the gains, Mr. Chairman, and it’s called fear. If colleagues around us are being laid off and cut back, we can’t help worrying that our jobs may be next. But is it good news? Americans already put in more hours than workers in any country in the world – and that doesn’t include the uncounted shadow work that technology makes possible after the regular workday ends.
