Adjacent point based on your comment: I want to emphasize that this is not a difference in understanding between the
rich in the traditional sense and the
poor in the traditional sense, at least in the US. I know people with significant multi-generational family assets that don't call themselves
rich. This crowd is largely (obviously not exclusively) white, US-born, and from the upper end of the middle class going up. Based on my interactions, very few seem to have experienced significant portions of their life without basic food, housing and medicinal security.
A whole lot of people within all striations of the middle class assume that they kind of "get it" through osmosis because they're not rich and they were probably friends with poorer people growing up. But barring stereotypes, we always assume other people's lives, problems, decisions, challenges, and affordances are more similar to our own that others. People from the upper end of the middle class are often blind to the difficult realities of growing up lower-middle-class in meaningful ways that create similar cultural discrepancies.
