Things in poor neighborhoods are done differently than in middle- and upper- class neighborhoods. People that grow up in poor neighborhoods develop behaviors, customs, and beliefs that are different from other neighborhoods because they are part of surviving in the struggle. When they move on up, some of those behaviors, customs, and beliefs are no longer necessary and can even be harmful (e.g. strong reactions to perceived attacks). Others may actually provide an advantage (e.g. living through power outages). Regardless, these changes can cause a sense of estrangement from their childhood and original culture, leading to some resistance. Given all that:
What did you change and what did you keep?
Poor people more often have the kind of reaction of “Oh, that must have cost a lot.” whereas richer people will simply say “Yeah that’s good for you, it’s important to get the good stuff”.
Or, it’s knowing how fancy something is and then having to one up people. Money is involved but perhaps not explicitly mentioned, depends on the purpose though.
