> My point is that different people look up (or down) to different people by different criteria: "net worth" interests competitive capitalist adventurers, "who your parents were or where you come from" remains a high priority when someone is wealthy enough for their lifestyle.

I certainly find it plausible that if A and B are of roughly similar wealth, but A was born into wealth whereas B lucked/worked/married into it, A might see that as a reason to look down on B.

However, I suspect if A was born into $100 million and B lucked/worked/etc into $100 billion, then all else being equal, I doubt A would look down on B in the same way. I expect they'd more likely view B with envy, as a potential business opportunity for themselves, as a friendship which might give them access to things they themselves can't afford, than as a social inferior. When the gap in wealth becomes big enough, it tends to drown out all the other factors.
