You conveniently choose to ignore the cited research that says that employees are "happier" when they work 4 day weeks. Or are you simply being pedantic and arguing the use of "miserable"?

If human civilization is to go further, we need to recognize some of our generic assumptions. Work is a means to an end, most commonly a means to support oneself and one's family. It should support us in our basic needs (shelter, food, clothing), and allow us to put our creative and intelligent side to better use.

Sure, some would spend all of their time playing PS4, but by opening up opportunities for everyone in the civilization, civilization as a whole should see progress.

If you don't believe in benefits of the civilization and how it has advanced through history mostly through people with spare time (usually higher classes, but with spare time becoming more accessible, through everybody in the past ~100 years), I am sure you are fine with a bigger, stronger dude walking in and taking your car keys and driving off (that was the status-quo at a distant point in history).
