No, that is just accounting of salaries. That doesn't calculate the value/worth of the work and hence can't be used to determine salaries. That's circular logic.

That is not really what I was asking for or my parent talking about. We were talking about specific salaries. Engineer X wants Y salary. justified or not? You are suggesting revenue/hours.
With that logic, everyone gets the same salary and you would also value the identical work differently depending on the revenue (which might or might not be justified)
