I think the 'objective' methodology for figuring that out would be either a marketing study, ethnography or something else. My rule of thumb is to see where the majority of advertising money is going. The rich and elite are usually more susceptible to advertising schemes because they have the ability to replicate the lives that marketing portrays. That is the beauty of owning massive amounts of private capital, while it is selling an unattainable material lie to us proles, it is only selling an unattainable spiritual lie (that if you are unhappy despite money and success, consumption will solve that unhappiness) to the wealthy and elite. They can actually attain the material reality portrayed in advertising, so it is just a matter of getting their eyeballs on it.
Also, within capitalism, isolation is usually the rule of thumb. The elite of capitalism wish to stand apart from the mass of humanity, as titans and utilitarian betters.
