> Unless you're at the bottom, you're also at the top as far as people less fortunate than you are concerned.
Analyzing this situation in terms of a qualitatively homogeneous property differing between people only in magnitude (income or wealth) is a mistake, in my opinion. (And so is taking a psychological approach.)
The most important thing the people at the ‘top’ have here is not any particular amount of money or income, but a radically different relationship to labor and the workplace than the mass of people who work under them. They have special powers (e.g., the power to set wages) and their income comes not only from producing things or providing services using their brains and muscles, but through owning and managing capital. At the very peak of the top, there are owners of capital of whom virtually no management at all is required.
It's because there are people, and of necessity a minority of them, in such a position at all, that the interests of society (as well as its privileges) are divided in such a way as to produce the inequality we have.
When wage laborers _do_ have control or input over things like wages, we _don't_ see the same enormous gaps between the highest and lowest paid employees at those firms. And in the case of that more agreeable outcome, too, the cause is not psychological— it's not that wage laborers are kinder or more generous people than executives, but that their position entails certain interests which are different from those of executives, and given the chance they will guide the firms they work at accordingly.
