Not saying I disagree but to play devil's advocate here - wouldn't them spending on luxury items still benefit society overall rather than them keeping it locked up somewhere? Working class people are the one's making and selling the luxury items and once injected into the economy the money they spent on said items would be taxed further and spread around as others spent it.
