Right. But, a lot of so called work doesn't really produce anything tangible.
Many jobs are the equivalent of a daycare center for adults. Designed to keep people *busy*.
As I mentioned above, there are many jobs that could disappear and society would not fall apart.
OTOH, there are many jobs that are necessary. Blue collar jobs where people make, build and fix things. Service industry jobs where people provide products, goods and entertainment. Transportation-related jobs are vitally important to an economy. Entertainment is a job.
The pandemic actually showed that people could work from home instead of commuting back and forth and causing traffic jams.
In most white collar jobs, 60% of the work involves a computer and the other 40% is meetings.
In the future, many of those computer-based jobs will be replaced by AI. Higher unemployment.
It is true that many people who are accustomed to the routine of being a hamster on a wheel when told to get off don't know what to do with themselves. Some of them atrophy and die.
I know a whole lot of people who have been retired the majority of their lives. Never really worked anywhere.
Most wealthy people and their families don't have to work. They aren't running around committing mass suicide either.
The number of people who can be supported by one person with millions or billions of dollars is exponential. The same applies to countries with countries with socialist governments.
There's a reason we hear talk of reducing the number of hours per week that people work. Provide more free time in an effort to increase quality of life.
