Unapologetic materialist here ... I won't turn down a nice house, a sports car, an audiovisual studio, my own music club. But I'm not into them for "status," or to keep up with the Jonses. They're tools for a great life. And no, they don't define me ... how I use the tools defines them, not the other way around.
That said, I totally respect your viewpoint if you think otherwise. Diversity is not only good, but necessary.
