Given our current medical crisis, it's easy to see how valuable doctors, nurses, and first responders are to the world. However, their primary role is to save lives at whatever cost or effort. Their role is defined by how well they do their job, but they are earning money for themselves and only for themselves. When lives are saved, it's the hospital or city who gets credit, but those in the trenches know who deserves the praise.
Famous actors, musicians, and athletes do not save lives on a daily basis. They train, practice, and perform for individual and team success, and make money primarily for production companies, record labels, and team owners. While most will never compare them to doctors, nurses, and first responders, they nonetheless consider what they do important to cities, fans, and countries. And, most don't have to do their primary jobs well, their name alone can put fans in the stands, which means money, money, money coming in.
Doctors, nurses, and first responders will never make the money they deserve for saving lives, not to mention putting their own lives at risk dealing with deadly outbreaks. But, that's the profession they chose, and many do get paid well, even when there's no medical crisis. How do you put a dollar amount on a doctor's decision to treat a patient with experimental medication, against traditional thinking just to save a life? You can't. Most just thank God they did.
It's a matter of how much their employers can make from displaying them. You and I don't agree with how much they make but we have to admit that it's an objective measurement. How could you rate the value of a teacher, a fire-fighter, a nurse, or an orderly, without being subjective?
