Seriously?? The Trauma Surgeons i work with don't have easy jobs either, and i think THEY deserve a 28 million dollar salary over Disney's CEO. Lots of people dont have easy jobs.... Doesn't mean they should get paid 28 million dollars...
It's not just whether the job is easy or not, it's how many people are qualified to do it and the demand/market for the services.
For example, there is not a huge number of trauma surgeons, and the demand is fairly high, so they are compensated well. But there are many of them, so they cannot just "name their price".
There are many people able and willing to work retail jobs, so the supply is high and the demand is fairly low, so the pay is far less. In times of high unemployment, the supply is even higher, so the pay is even lower.
There are very few people who can hit a 98 mph curve ball, and many people willing to pay to watch a person do that, so the pay is very high.
There are many people willing and qualified to work as production assistants for TV shows, so the pay is low. Far fewer are qualified to be producers and directors, so the pay for those positions is much higher.
There are few people who are good at high-end sales of complicated products, such as large-scale software suites, medical/pharmaceutical sales, etc., so the compensation is higher.
And lastly, there are VERY few people qualified to be the CEO of a multi-billion dollar integrated media and entertainment company that returns billions in profits to the shareholders year after year, so the pay is very high.
It's all supply and demand, and I'm sorry, but the demand for a qualified CEO is far higher and the supply is nearly infinitely lower than for skilled CMs. It's not a statement on the value of CMs, as I know they take great care of me and my family and are on the front lines every day, but a company cannot compensate based on the "good feelings/warm and fuzzy factor" and stay in business for very long.
