In regards to warranted compensation, they aren't remotely the same job.
The CEO of my hospital system is captain of the ship. He, with the help of his board/committee, not only keep the boat afloat, but also need to steer the boat -- avoiding debris/icebergs in the water -- and win the regatta that they are simultaneously in with other hospital systems.
Big deal, right?
Well, the boat also happens to be worth 10 billion dollars and have over 62,000 workers on board (i.e. the rowers under the deck that keep the boat moving forward).
The captain leads the ship and gets to eat as much food from the pantry that it can withstand. Rowers are largely replaceable. Whether you get fed up with small rations and jump ship, or they decide to throw you overboard -- you can be replaced with a viable replacement rower who will happily take the job and enjoy the meal you turned down.
There's still the option for you to build your own boat and set sail. However, the trend seems to be that the tiny dinghies are just getting run over or overturning in the wake of other larger ships.
