Why get paid while your socialising with people in a work environment when you can isolate yourself at home and talk to randoms on the street or join clubs at your own expense and time. Friends can be made anywhere BUT work now apparently. Why do kids need to go back to school? They can sit at a desk at home. They can make friends elsewhere and they don't need to go to school for physical activity. They can do that in any club, group meet, sport, hobby whatever. Schools for learning after all, not making friends.
