I think this is an important point that many people seem to gloss over when discussing what humans _deserve_ to be paid.
Many believe the uniqueness of a skill set or how much physical stress is inherent to a position should be the only factors which increase a salary.
But the point you highlight here says that the amount of soul-crushing misery a position entails should also play a significant role when determining salaries.
It seems that in many countries, companies can get away with paying soul-crushing positions so terribly because so many people are coerced into these jobs--forced to choose between incredibly soul-crushing, low paying positions or watch their families starve, become homeless, not be able to afford medical care etc...
Which leads me to wonder if there are any societal changes we could make in order to nudge salaries to reflect when a job is mentally abusive. Similar to how pay typically reflects when a job is physically abusive.
I'm guessing Denmark has a decent safety net which forces companies to actually factor in mental abuse of a position when they're formulating salaries which ensures their citizens are compensated accordingly?
How so? To artificially keep salaries high?
I would have no problem with producing locally where it makes sense, but not to avoid minimum legal standards for wages (or for that matter for other things like environment).
A basic income would work here. If people aren't forced to take a job out of economic necessity then unpleasant jobs will need to pay more to attract people to do them.
