> No one consciously favors the rich kids; it's the confidence and status that they carry with them that gives them the advantages. They expect to be treated with respect, even by powerful people, and most of the time, that's what happens.

Yes this is a very important and subtle dynamic that this group uses to great success.

Though I think it's worth mentioning that it's just one of a few archetypes. There's also the street-smart working class hustler type who is just absolutely relentless and tireless as a self-promoter and takes no opportunity for granted, always puts in the extra effort. That approach can be effective too.

What's common to both is that they are not passive, and that neither believes in a myth of "fairness" that promises them rewards simply for their work ethic. What rich and poor have in common -- and the middle class often misses -- is a keen understanding that the system isn't fair and isn't designed to be fair.
