Yes and no. I live in a VHCOL region and I'm in a high income profession. As a result, my work peers, neighbors, etc are typically high-income and often a lot wealthier than I am - frequently the kind of folks who came from at minimum upper middle class backgrounds, went to elite schools, etc.
For example, in my circles, it's perfectly normal for people to drive luxury cars, own multiple homes, belong to country/yacht clubs, etc. I've got some neighbors who are in the nine and even ten figures NW - the kind of people who collect exotic cars, own large yachts, inhabit big estates. So, my idea of stealth wealth is vastly skewed. In my environ, I live a stealthy lifestyle but on this forum would probably not seem all that stealthy.
Wife and I believe in living below our means - for example I drive a nice model car, but its clocking 14 years old now - still running nicely, just needs plenty of upkeep. And we looked at some very large homes, but settled on something that would not be considered grand. I did have to remind DW to stop calling it "small" - our retirement house is on the modest side for our area, but its definitely not small relative to a lot of our extended family who might take offense at the characterization.
I do prefer to fly below the radar, but that's sometimes tough to do in my case, so try to find a middle ground of being able to blend in my high octane surroundings while not coming off too whatever outside this bubble. In retirement, will be easier to be stealthier except for being "retired" which I can already see, seems to unsettle people who are worried they'll never be able to retire.
EDIT:
P.S. Should note that I was in no way, shape, or form born into this kind of environment - quite the opposite. In childhood, I have seen and experienced poverty and extreme financial insecurity up close! So, these opposing money cultures are a bit of a mind bender for me. DW grew up middle class, so less of a disconnect for her. But, in both our cases, we do try to play down our situation with extended family, as our assets would be more than all of them out together - they might guess that but its critically important to maintaining those relationships that they not have it rubbed in their faces.
The only people who know our financials are my financial advisor and my estate attorney.
EDIT #2:
In terms of stealthiness, we tend to spend money in less obvious ways, compared to our extended family. For example, some of them have always driven nicer cars than DW and I. For many years, we would be the ones showing up at any family gathering in a rusty old beater, while the rest were in shiny new vehicles. And we don't do social media, whereas, constantly seeing others posting their fabulous [party, vacation, new boat, etc.]. Where we spend $$$ is on our home(s), on wellness/healthcare, on help (housekeeper, gardener, pool guy, etc.), less visible stuff.
