It's much more complicated than that. One of the beautiful things about business, or any cooperative effort, is that the sum of the group/company is worth more than the sum of value of individual effort. 2+2=5, if you will.
The problem, when it comes to human nature, is that once the total value is determined (market cap, annual profit, ROI, etc), individuals tend to over-estimate the value of their individual contribution.
It is not just airlines. Uber drivers say they provide the rides, there would be no service without their effort. Uber says nobody was paying you to drive before we launched our platform. Both are correct. Foxconn employees say we're building all these damn iPhones, no other facility or workers can produce at this volume. Apple says if we didn't design and market such a popular product you'd have nothing to build. Again, both are correct. A film director says, look, the movie I made grossed $400 million -- and the studio replies, which you could have never made without the $100 million budget we risked, up front.
