^ this, he was specifically referring to working longer hours. He explicitly stated it.
Which is strange because Germany works only 26 hours a week and has a powerhouse of an economy. Also it's strange because our economy is more productive than it's ever been, it's just that laborers have had compensation basically stagnate for 40 years. Also it's strange because many of those part time workers do want to work more, so it seems even more obvious that the problem is elsewhere.
