Most rich people weren't born rich. That's the part that all these theories about an oligarchy leave out. Some rich people were born rich. But most rich were born non-rich, and are overachievers who became rich.
Overachievers are more likely to be greedy. Overachievers are also more likely to hustle their way into power. That's just human nature. Some people always rise to the top. There isn't some big conspiracy.
So is society supposed to repress overachievers? Is society suppose to limit wealth, or limit the communication overachievers have? How exactly can an elite be prohibited?
They are rich people. And most of them are born with a silver spoon on their mouth. You will still consider the not oh so rich people that came up rich like Mark Zuckerburg because of their innovative ideas. Overachievers really tend to be greedy and I think that is not bad at all.
The problem, of course, is not over-achievement. The problem is that the system is rigged in favor of the top bankers and politicians. The entire system we live in is based on theft and deception.
See how the system really works.
