The chief motivation for System writers ostensibly remains greed: career and money.
The irony is that all follow the standard literary path, which takes them in the opposite direction of their goal. They'll pay $50,000 or more to accept extremely low odds of making it as a writer; to become one of 40,000+ similarly labelled with said degree. I suspect the badge itself-- "MFA"-- for most of this number is the real motivation. This certifies the person as a "writer" and allows him or her a kind of respectable, if useless, attainment.
For others, undergrounders particularly, the writing itself is the goal: the expression and construction of authentic art.
The ULA campaign offers an added bonus to the independently-minded writer-- the opportunity to make literary history, as we've done with our protests, our actions, our never before seen in-your-face excitement. (The status quo is reduced to presenting weak substitutes like the Dishwasher guy.)
Most non-underground writers are embedded in the literary past. Embedded-- incapable of breaking out of their artistic assumptions and prejudices. Even when they write about literary rebels of the past, it's in a thoroughly dry, academic way, their ANALysis coming through the prism of their politically-correct institutional brainwashing.
The Underground Literary Alliance offers literature as an adventure and a challenge. With us, the writer isn't one of 40,000+ trained and certified automatons, but a rebel engaged in the battle of ideas. We're guerrillas and prophets, a band of upstarts, vanguard of literary change.
Our fearlessness is our greatest strength. There is nothing appealing about an endless parade of artistic apparatchiks. Someday this nation's literature may devolve into an Age of Sheep. We're here to say: That time has not yet arrived! Exciting days remain.
