Background: MFA in Creative Writing is a degree taken by aspiring novelists. MFA stands for Master of Fine Arts (and not multi-factor auth ;-)). Poetry, fiction, novels, personal essays, and non-fiction are all sub-genres, but I think they are discussing creative writing in general.
The essay and the linked essays together seem to say the following:
Master of Fine Arts (Creative Writing seems to be the topic under discussion) [MFA] is a degree of the privileged.
A majority of those who graduate with an MFA, end up teaching MFA courses.
Those who teach, try to publish more via friendly publishers (university/independent). Pressure to publish for tenure. Quantity over quality.
Compares NYC writers vs writers who have MFA. NYC good. MFA graduate bad. (My thought: What about the rest of us who are not from NYC and have not taken an MFA?)
