Personally, I enjoy working hard - usually more than 40 hours per week. But we should distinguish between working for others and working for oneself. Working for oneself can be education, passion work, or anything that energizes you. Working for others is also necessary for most people but reducing the weekly commitment gives people more freedom in their lives and makes them happier and more productive.
For some, the extra time away from work gives them the freedom to spend more time with their family or children, or spend more time on their hobbies. But ultimately it makes these people better contributing members of society.
One belief I certainly don’t agree with is the idea that working less for others makes you a lazy person or a less contributing member of society. People need free time to care for themselves and others, vote and participate in democracy, and do their laundry. We will be better off with less time committed to working for others.
And of course I cant help but plug 30 Hour Jobs here since it’s very much relevant: https://30hourjobs.com
