Sadly, most Americans are simply not educated these days, despite near record levels of people going to college. But I do think we have to take these death of culture essays with a grain of salt. Adorno and others wrote long books about how horrible middlebrow and popular culture were, and this was in the late 1940s and 1950s, which is an era many of us consider to have produced some of the best movies and music of all times.
I think plenty of people are educated....just not culturally educated! I work with a ton of people that have many degrees and are very smart (some brilliant) that haven't set foot in a museum, listened to jazz or read books since college....seems strange to me but that's what I'm seeing.
