there is something analogous - it's not the same thing, but it mirrors the structure - in the relationship between highbrow and lowbrow and the relationship between the aristocracy and the lower classes.
Which is that they get on better with each other than do with the bourgeoisie in the middle.
historically, the very posh and the peasant had similar passions, like gambling, drinking, hunting etc.
whereas your bourgeoisie was the class that invented puritanism, methodism, teetotalism,commerce, investment - a cautious, prudent, resources-conserving approach to life.
you see it with horse racing, that intermingling of the very posh and the lumpen at the race course
i've observed this is life too - intense friendships i've seen between actual nobs (as in the nobility) and people from very working class backgrounds. there's a similar attitude to pleasure, a live-for-the-moment recklessness - unlike your careful middle class types like myself who come from what i would characterise as an uncomfortably off background, where there's a background hum of financial uncertainty behind the bourgeois facade.
your aristos don't give a fuck because they have everything and were raised entitled; your proper proles don't give a fuck because long-term, providential thinking doesn't make sense, you live for the weekend

a musical counterpart to this aristo / peasant thing, would be composers like Bartok going out into the Hungarian countryside and notating folk songs and stealing ideas from them to invigorate their work.
