I think this is one of the biggest bonuses you get as a technical person; you can live with roommates and drive a beater car, if you want, and it's not a problem when getting quarter-million dollar a year jobs.
A long time ago, I had a roommate who was trying to make it as a realtor. He though his (actually quite nice) not exactly new honda accord was a big handicap for him. I mean, I don't know if it was or not; I know little about the selling side of real-estate, but I can tell you that most people who do sales or management feel that their symbols of wealth are really important to their job and their income.
Devs in SF display status in other ways. HN karma? Exits? Economists call those “hard to fake” status displays.
No, developers display status more directly, by pointing at a thing and saying "I did that" - or on a lower level, simply displaying intelligence and domain specific problem solving ability.
