You make a convincing case that their are forces that encourage very rich people to congregate relatively close together, I don’t think its the main force behind what is going on but I can see that it exist. Other forces also exist, like those I outlined above. Mine is not a productivity argument, and you could if you wanted even lump my suggestion under “there were other rich people there to network with” where “network” here means “marry” and “rich people” here means “people with a career, not a job.”
