>I can afford to get the new iPhone every year or two if I wanted

Maybe that's what the difference is. Being able to afford these things means you might not feel a similar need to posture that you can afford a certain lifestyle that you really can't. I'm guessing that at minimum wage most would struggle financially especially in a large city like NYC, so being able to pull the newest iPhone out of their pocket might be their way of assuring themselves and people around them that they are doing alright financially.

My wife has had more contact with poorer communities. And she believes it's partly to maintain the appearance of wealth and status. I suspect it's also a luxury within reach versus those which seem impossible: homeownership, choosing ones employer, world travel, etc.
