You essentially need to work a full-time job to survive. Ideally, a somewhat good job to be comfortable. But if you want, say, a place to live, a steady supply of food, and your medical needs taken care of so you don't die prematurely, you need to be working full-time.
Yea standard of living has increased. Can't you want olden-days level of healthcare, accomodation, food, etc. but less work?
