Who are the elites everybody talks about? Rich people?
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?
It is not at all these people that we've been talking about. I'm sorry if I haven't been explicit, but I've been talking about the top politicians, central bankers and high financiers who have the power to issue money, 'safe' debt, and highly profitable financial assets.
There's a big difference between people who can conjure up wealth out of thin air and those (however rich) who can only profit when other people want to pay them. Over-achieving is probably required for the latter group. (Although we should remember that the markets that over-achievers in the real economy sell into have themselves been distorted by the issuance of money and debt by the top elites -- but that's an issue for another time.)
