The de-structuring of jazz has been linked to its slow death but there are people who defend this kind of improvisation because they feel that jazz like any other music form must be democratic in nature. Cornel West (1995) tries to defend Parker's de-structuring of jazz in his book, Keeping Faith: Philosophy and Race in America, "I use the term "jazz" here not so much as a term for a musical art form, as for a mode of being in the world, an improvisational mode of protean, fluid, and flexible dispositions toward reality suspicious of "either/or" viewpoints.... It is true that the materials of jazz were not discovered at the court of the Esterhazys; but the rest is sentimentality. Improvisation in jazz is not a release from structure, and structure in jazz is not an experience of oppression. Jazz is no more democratic than any other art. It is governed, like all art, by an either/or: either you do it...

"
Jazz is hence a dying form of music. It suffers from low consumption, slow growth, racial associations, demographic challenges and wrong de-structuring. There are many reasons why Jazz is no longer a popular form of music as it was when it first became known in the U.S.A revival doesn't look imminent but only time will tell if there is any hope left for this once popular music genre.
