For all modern society's promises of leisure, liberty and doing what you want, most of us are still slaves to a schedule we did not choose. Why have things come to such a pass? Well, the forces of the anti-idle have been at work since the fall of man. The propaganda against oversleeping goes back a very long way, more than 2,000 years, to the Bible. Here is Proverbs, chapter 6, on the subject:
Go to the ant, thou sluggard; consider her ways, and be wise:Which having no guide, overseer, or ruler,Provideth her meat in the summer, and gathereth her food in the harvest.
(I would question the sanity of a religion that holds up the ant as an example of how to live. The ant system is an exploitative aristocracy based on the unthinking toil of millions of workers and the complete inactivity of a single queen and a handful of drones.)
