This model is way too simple. People don’t distinguish themselves between those they don’t deal with. No one’s going to confuse a social worker with the genuinely wealthy, but they could pass for a professional like a doctor or lawyer. Equally they could be mistaken for someone of the class of their clients if they dress like them. The social worker will try to dress like the successful professional. The professional is not going to be mistaken for a poor person. If it happens they’d laugh unconcerned and move on. But they are probably socially exposed to genuinely wealthy people or the extremely professionally successful, businessmen, parliamentarians or congresspeople, executives. They could move into these circles themselves or marry into them.
People define themselves by those they could plausibly be mistaken for, not the full range of possible social roles.

> Everyone wants to look like they are a member of a higher class than they actually are. But everyone also wants to avoid getting mistaken for a member of a poorer class. So for example, the middle-class wants to look upper-class, but also wants to make sure no one accidentally mistakes them for lower-class.
> But there is a limit both to people’s ambition and to their fear. No one has any hopes of getting mistaken for a class two levels higher than their own: a lower-class person may hope to appear middle-class, but their mannerisms, accent, appearance, peer group, and whatever make it permanently impossible for them to appear upper-class. Likewise, a member of the upper-class may worry about being mistaken for middle-class, but there is no way they will ever get mistaken for lower-class, let alone underclass.
