Why is asking about money rude?
I get why asking someone randomly is rude, but why is it rude if it’s got to do with the conversation? On a tv show someone wanted to buy something really expensive and someone else asked how they could afford it, and another person said it was rude.
There’s also a cultural element to it — the dominant US culture has a bit of a taboo regarding discussing money openly. It often confounds visitors, immigrants and people who don’t share that culture, since it’s not a universal thing.
Yes, that is true. It’s not just the US, but it’s not universal either.
