These types of threads always have me scratching my hear. Most of my friends are mainstream, in the sense that they maybe save 10% or in some cases they probably save -5%.
No one ever said anything to be about my 20 year old car. (Fairly recently upgraded to a 4 yo car that we will likely own until it's about that age, hopefully). No one cares that we only own one car. (I've gotten questions about whether it's hard, whether I feel trapped, etc., but they have always seems just curious or maybe slightly confused, not judgemental or condescending.) No one ever said anything about our fairly modest townhouse we lived in, or the fact that I wear make up maybe 1/mo, or anything else. So many people have these stories about people commenting, and I just don't get it because nothing like that has ever happened to me and that's certainly not because I hang out with like-minded people. Yes no one has ever insulted any of these things. I wonder why that is?
I agree with you. Do I just have less judgmental friends/acquaintances, or what?
My own experience has been that, unless you make it a point to harp on about these things, no one cares. About either frugality or lavishness. Both are just "meh" events.
Sometimes I drive a shitbox (my parents' old car), sometimes I drive a fancy car. Besides car enthusiasts no one's ever commented on my car. Sometimes I dress nicely in a suit and tie. Most of the time I go to work in track pants and a sweatshirt, and sometimes I wear the same clothes 3 or 4 days in a row cause I have a lot of pairs of track pants and grey jumpers. No one's ever commented one way or another.
I also feel a bit surprised that there's apparently so much social judgment on either extreme. I suspect for the most part if you're not drawing attention to yourself you can do whatever you like (short of going naked, or wearing royal robes, or driving a Ferrari) and not be judged.
Then again maybe it's just middle class privilege talking. The comfortable middle class like us do get to be invisible and go without judgment, more so than, say, a poor person with bad teeth and bad grammar.
