> As such, a social class is, yes, a lossy abstraction taken from the point of view of any given individual, but it's not like it's failing at being a good category because this is so. That's just, like, how concepts in general work?

Sure. What I'm pointing out is that using the concept of social class as the lens through which you analyze all human social interaction, and draw conclusions about the entire fundamental organization of society, is a case of erroneously universalizing a lossy abstraction.

And when people obsess over social class to the point of characterizing every question, debate, or controversy in society as a manifestation of "class struggle", and criticize people for framing their relations with others in society through some lens other than social class, isn't that clearly what's happening? Isn't that what happened right here in this thread, and led to us having this very debate in the first place?

> I wonder what politics looks like following through with your argument? How do we conceive of things like the "public best interest" if any given classification is doomed to not capture people actually? What is the "public" here? Are there children? Seniors? Veterans?

Well, that's exactly the point. Maybe the answer is that the question doesn't pertain to "the public" as some unified aggregate, but is actually something that different subsets of the public need different approaches to. Maybe the best interest of "the public" aggregated into a singular entity is to to figure out how best to disaggregate the question.
