I tend to think that Weber was correct that peope only behave as social classes during crisis and hardship but that the rest of the time they behave more as status groups, which can be culturally specific, so for instance in a racially conscious society that status criteria will be more important than social class in the making and breaking of relationships, marriages, even business deals etc.
However that's strict observation rather than evaluation, I've got to confess to some sympathy with Orwell's version or vision rather of a classless society but at once I think that some conservative arguments about class having at a time constituted a social, organic and mitigating factor between state and individual or community is interesting. One endorsing classlessness, the other endorsing class but both for compelling reasons.
I just had to think about it recently after seeing conservative propaganda t-shirts which read "the left has no class", I thought, why yes, yes it doesnt but I understood at the same time this being divested of class was being stated in a prejorative sense and I reflected that class can be considered a good thing to have too. It was clever, in the way that Saatchi and Saatchi's "Labour Isnt Working" campaign posters for the Conservatives before 1979 were clever.
