Can we extrapolate Vance’s experience and apply it to all of this culture?

In the introduction to Hillbilly Elegy, JD Vance calls Appalachia a “culture in trouble.” One main trouble, he explains, is this: “Hillbillies deal with uncomfortable truths by avoiding them or by pretending better truths exist.” Vance also tells us, “My primary aim is to tell a true story about what that problem feels like when you were born with it hanging around your neck.”
