I think that ultimately stems from different workers' rights in US where people work even if sick due to the sick leave limits and low mandatory vacation days.
I'm quite sure people that are independent/self-employed in Europe work comparable numbers because they too will likely take much less vacations and sick days.
Could this be in the opposite direction, where the richer you are, the less you need to work?
Edit: Elaborating… in my experience entire countries will be on holiday for up to a month at a time, while the US offices are chugging along. (And this by and large isn’t true the opposite direction, except for Thanksgiving week.)
I’m not saying it is good or bad either way, but the US prioritizes work far more than other OECD / developed countries.

The craziest thing to me about the US is the number of vacation days given, but not used.
If every did their neighbor's laundry (say) and charged a fee, then everyone would be doing the same amount of laundry and have the same amount of money, yet GDP would rise?
Two economists are walking in a forest when they come across a pile of shit.
The first economist says to the other “I’ll pay you $100 to eat that pile of shit.” The second economist takes the $100 and eats the pile of shit.
They continue walking until they come across a second pile of shit. The second economist turns to the first and says “I’ll pay you $100 to eat that pile of shit.” The first economist takes the $100 and eats a pile of shit.
Walking a little more, the first economist looks at the second and says, "You know, I gave you $100 to eat shit, then you gave me back the same $100 to eat shit. I can't help but feel like we both just ate shit for nothing."
"That's not true", responded the second economist. "We increased the GDP by $200!"

It's not just that some work isn't counted. It's also that work is counted based on monetary remuneration, even if it's contribution to the general welfare is very low or negative.
