Another angle when it comes to comparing incomes is the mistake that we make by presuming that everyone has OUR particular life circumstances.
When I was making $16K at Skyway, I was able to pay for my rent-controlled apartment, put gas in the car, food in the fridge and occasional trips down to Water Street for Leinekugels and Real Chili.
So when I looked at people complaining at the starting salary at another airline "only" being $50,000, algebraically, I made the mistake of thinking that I would have an extra $34,000 in my pocket at the end of the year and what kind of idiots are they to complain about making $34,000 more than I am! How can THEY be broke when I'm making ends meet at $16,000? What are THEY doing wrong?
Well, nothing. We all have dissimilar circumstances and needs. Some people are blessed with healthy children, others have children with health challenges. Some folks have Porsches, others have their original Honda CVCC's. It just really all depends.
Entrepreneur? I hope you become a trillionaire.
Harvard B-school grad that becomes an airline CEO, slashes jobs, outsources and doesn't do anything to actually build, modernize or grow an airline, I don't see why you should earn a dime more than your captains.
Fred Smith? You go, boy! You had an idea, grew it, perfected it. Make it rain!
Leo Mullin? Good lord, my cat, while leaving a steaming coil in the catbox had better leadership skills and business acumen. Far FAR overpaid and did more to destroy than build success.
