Sam and Dean are coded working class. Very much so. And they are homeless, although they have a car and they manage to live out of cheap hotels, mostly because they are scam artists. Sam was on the verge of breaking into the middle class through education and scholarships, but he gave that up to return to the hunt.

It's very frustrating too because I think a lot of the stuff they say that academic fandom calls "misogynist" isn't really, but it is the way working-class white people talk.
