Two of my aunt/uncle pairs are extremely affluent (mansion-level affluent). One is extremely poor. My mom and I aren’t exceptionally skewed either way. I mean, I’m going to grad school so we’re not exceptionally poor, but we’re not really super rich either. My dead aunt wasn’t very rich.
It’s changed over time though. When I was little everyone was pretty much middle class. One uncle was in construction and became really important at the company, and thus rich, and my aunt (married to him) got lucky with a manager that liked her at the liquor store she worked at and now is second in command of a large chain of liquor stores.
My other aunt married into wealth with her second husband, also in construction.
The poor one has always struggled, but all my family except my mom and me live in Wisconsin. This aunt did education stuff (not a teacher, but in the field), and she’s married to a career fireman. They got hit really, really hard by the stuff with Walker. That caused more friction than anything else in the family, because the rich ones are extreme Republican, and very openly supported Walker’s reforms. “Of course, it’s not personal. We don’t want it to affect you, but it needs to be done and it’s definitely the right move” wasn’t what she wanted to hear (especially along with a staunch refusal to loan her money to help her through the rough patch, right or wrong it definitely was the last straw for her).
