It's not just old people:
"in 2000, if you happened to be a 20-year-old man with less than a Bachelor's Degree--and when I say 20-year old, I mean in their 20s--21 to 30. About 8% reported not working at all during the prior year. That number, today: About 18%."http://www.econtalk.org/archives/2016/11/erik_hurst_on_w.htm...
