The mere fact that they can afford to live in a 1-bedroom in the EV is, well, evidence against that fact. You're not even part of the underclass in Manhattan if you can do that.
If you call yourself part of the underclass, either you're: Forgetting that they exist, or you're pretending that your economic situation is somehow roughly equivalent. I don't think you need to keep that on your mind every single second of the day, but at least be honest about it.
For instance, New York City made significant efforts to include a large number of affordable housing in many recent developments. People within a certain income range(30-100k ish) can apply for these apartments at a significantly reduced rent. This allows people who work middle-income jobs to at least live close to work. I'm not arguing the against the merits of these programs as I think income diversity is good, but this combined with the reality that many new developments included mainly luxury units or affordable units without much in-between, causes a significant rent burden for many New Yorkers making 100-200k.
Contrast that to say taking a 15% salary reduction to live in Nashville, that same person now probably lives much more like the upper-class of Nashville than the lower class.
