Fear of salient relative wealth, incurring disapprobation and intimidation, is and has always been widespread, and most acute over narrow social intervals and short geographical distances. In the present democratic phase this has produced reverse sumptuary self-regulation, where it is socially unacceptable to dress in ways that are perceived as claiming relative advantage. Cars are a partial exception to this rule, partly because so few are actually owned by the drivers, and partly because the owner is shielded from attack by the velocity or potential velocity of the vehicle. The rich dress down, but drive up (and park in a secure location).
