Apart from the winner, it is overwhelmingly male and overwhelmingly white. Now I'm not interested in polls (or competitions) that feel compelled to include women or black writers just for the sake of balance, and I think that this list is probably a fair reflection of the best of the best known writing in the US in the past 25 years. But doesn't that suggest a problem? I would suggest there must be other writers in the US who are producing equally good work, but they cannot break through into the cabal of old, white men led by Roth and Updike and McCarthy. They are not becoming well known.
It's an important point, because it feels to me that current American literature is not reflecting current American culture, nor is it leading it, in the way that my old mate Kurt Vonnegut insisted it must.
It is also noteworthy how few books have come from the 2000s. This, I would suggest, is related to the previous point: no matter how fine late period Roth is, for example, there is still a stasis in American fiction that will not be remedied until it allows some fresh blood to flow into its veins.
Step forward, for example, Percival Everett.
