We lack the requisite community of readers

An interesting insight from The Great American Novel: Will there ever be another? by Roger Kimball.

My point is that even if a new Melville or Twain, Faulkner or Fitzgerald were to appear in our midst, his work would fail to achieve the critical traction and existential weight of those earlier masters. We lack the requisite community of readers, and the ambient shared cultural assumptions, to provide what we might call the responsorial friction that underwrites the traction of publicly acknowledged significance. The novel in its highest forms requires a certain level of cultural definiteness and identity against which it can perform its magic. The diffusion or dispersion of culture brings with it a diffusion of manners and erosion of shared moral assumptions. Whatever we think of that process—love it as a sign of social liberation or loathe it as a token of cultural breakdown—it has robbed the novel, and the novel’s audience, of a primary resource: an authoritative tradition to react against. Affirm it; subvert it; praise it; criticize it: The chief virtue of a well-defined cultural tradition for a novelist (for any artist) is not that it be beneficent but that it be widely acknowledged and authoritative.
