I would guess that the median* wage on HN is probably around 5x what your brother-in-law makes. And I would also guess that many of us are perfectly content with old phones, old cars, and generally reduced consumption. Hell, I buy clothes at thrift/resale shops when I find something nice that fits.
What are people of means (relatively) seeing? Is it because we have more leisure time and can afford to filter the media we consume?
*I'm consciously using median because I would guess that FAANG and the coasts skew the mean.
