Note that I am not saying one side is inherently better than the other. I’m saying it’s a choice with consequences. It is essentially a question about what you value in life.
It might also be that Denmark is half the size of South Carolina (approximately). While the US is the whole size of the US.
We sadly gave up proper benefits/balance of life for higher income. Which of course hoodwinked us when economy tightened up. Some states have it slight better, but I haven't had a proper vacation since college. Unless you count being laid off with no notice.
Then you have loopholes as usual. Layoffs in some states SHOULD be noticed in advance, but only if it's something like > X people laid off. So why not instead make rounds of layoffs over the months? Great for morale!
That's probably not what you meant, but that's been my experience at every role so far. 5 weeks would be a dream for me.
