Are these really the people that should be required to work so much? Isn’t their job about handling life and death daily? Wouldn’t we want exactly these people to come fully rested to work every single day and be fully staffed?
I don’t know if there are jobs with similar stakes that are so carelessly staffed and disgustingly paid.
Capitalism can only provide basic services to everyone if those services are borderline slavery. It works for all the basic needs : food, healthcare, construction.
One might say it only works through slavery for everything because most of the non essential things come from other countries you can call colonies. But the thing is that without redistribution the basic services cannot be paid correctly.
