Demagoguery about greedy rich people or greedy corporate executives being paid 100 or 200 times their workers' salaries is a key weapon in the politics of envy. Let's talk about greed, starting off with Merriam-Webster's definition: "a selfish and excessive desire for more of something (as money) than is needed."
That definition is a bit worrisome because how does one know what a person really needs? It's something my economics students and I spend a bit of time on in the first lecture. For example, does a family really need one, two, three or four telephones? What about a dishwasher or a microwave oven? Are these excessive desires? If you say these goods are really needed, then I ask, how in the world did your great-grandmother and possibly your grandmother, not to mention most of today's world population, make it without telephones, dishwashers and microwave ovens? "Need" is a nice emotional term, but analytically, it is vacuous.
"Selfish" is a bit more useful term, and it's the human motivation that gets wonderful things done. For example, I think it's wonderful that Alaskan king crab fishermen take the time and effort, often risking their lives in the cold Bering Sea, to catch king crabs that I enjoy. Do you think they make that sacrifice because they care about me? I'm betting they don't give a hoot about me. They make it possible for me to enjoy king crab legs because they want more money for themselves. How much king crab would I, and millions of others, enjoy if it all depended on human love and kindness?
When Jack Welch became General Electric's CEO in 1981, the company was worth about $14 billion. Through hiring and firing, buying and selling decisions, Welch turned the company around and when he retired 20 years later, GE was worth nearly $500 billion. What's a CEO worth for such an achievement? If Welch was paid a measly one-half of a percent of GE's increase in value, his total compensation would have come to nearly $2.5 billion, instead of the few hundred million that he actually received.
There's another important issue: If one company has an effective CEO or a team has a star quarterback, it is not the only company or team that would like to have him on the payroll. In order to keep him, he must be paid enough so that he can't be lured elsewhere.
You say, "Williams, what about those golden parachutes for failing CEOs?" Paying a failed CEO, or a spouse in the case of marriage, enough money to go away quietly might be much cheaper than litigation.
