This just makes sense under our current understanding of economics and should be utterly predictable. If you do something useful then knowing you are useful is part of your compensation for doing the job. You don’t have to pay a person who wants to do their job or who gets a sense of achievement from doing their job as much as someone who doesn’t want to do their job and hates doing it, so you can cut salaries for teachers and nurses.
This is the tragedy of the commons where the commons being pillaged is people caring about each other.
