I think that's both fairly accurate, and seems to be more or less the norm across all cultures for most of history. Regular people are mostly benign, those in power tend to get worse the more power they have.
This poses an interesting question: what if this is in fact the most self-stable and therefore sustainable solution in the long term? And is it actually fair to assume that those in power benefit asymmetrically, or do they pay for it in ways that people without such means or ambition cannot even fathom?
If you live a normal, unremarkable life and generally get along with others, you probably won't have much excess material wealth, but you will also have relatively few enemies. The more you try to compete for the position of the top dog, however, the more you have to watch your back. Is it really preferable to sleep in a palace surrounded by armed guards because you are worried about assassins, just so you can own 50 nice cars you'll barely ever get to drive?
In other words, people who envy the rich and powerful always only ever look at the benefits, never at the price they pay for their privilege.
No, I’m merely pointing out that I would be wasting my time arguing with people who do not even care enough to make a semantically coherent argument.
