The thing that surprises me most about money threads on here is that some people seem to find it unbelievable that others can, and do, save quite a lot of money. I’m not sure if it’s because people assume everyone spends roughly in line with their salary, so there isn’t much left over regardless of income or whether it’s just not always obvious how much others might be earning. I suppose if your own circle isn’t very varied in terms of careers and income levels, it’s easy to assume most people are in a similar position.
AIBU to be surprised by that? I really don’t think it’s a normal way to think.
