That chart showing happiness being flat over 70 years is astounding. I’m certainly happier not having to hand wash dishes or clothes; no king who ever lived before then had access to magic lights that made his bad eyesight perfect, yet for all that the average person is just as happy as they were in the late 40s
The prospect of loosing access to those things can seem bleak, but to someone who never knew the luxury of a clothes washing machine it's just another chore. Why would they be any more unhappy? Everyone still does chores. We find ways to avoid letting them make us miserable.
