How Do You Define Morality?

It is more about asking whose work is more "valuable" the hospital manager or the hospital cleaner.

Depends on how you define value.
Supply and demand and bang for your buck makes the manager the clear winner here.
A better manager is going to give you far more profit and make your hospital far more valuable than just one good cleaner.
You can replace that one cleaner far more easily and one good cleaner will generate far less positive change than one good manager.
It has always bothered me when envious people gripe about CEO and sports figure's salaries.
Those salaries are a fraction of what they bring in profits to the business, if they do their job well they deserve it.
If the inventors and managers did not do their jobs well the laborers would not have jobs at all. Just because they put their hands on the end product does not mean they do the most "valuable" work.
Let them run the company for a month and see what happens, then get back to me.
Edit:
BTW, I have been on both sides and know it from both views... management deserves to make more money most of the time.
