You may be interested in reading Man's Search for Meaning by Viktor Frankl, which says (roughly speaking, and after Kierkegaard) that the striving to find a meaning in life is the primary motivating force in the lives of people, and its frustration creates an existential vacuum that leads to boredom, distress, depression, aggression, addiction, and the rest. He would agree that there has been a sort of crisis of meaning since around the middle of the last century, loss of religion and other societal conventions having a lot to do with it.

I think what you regard as "people engaged rabidly in the consumption of fiction" he might interpret as people living passively, bored and confused, abdicating a sense of responsibility for their own lives. I think he is a precursor to the Neil Postman line of cultural criticism, if anyone's looking for more books.

Man's Search for Meaning is a short and compelling book, he describes a way forward that doesn't involve resurgent nationalism or religious fundamentalism, and I've gotten a lot out of it personally.
