Half-way through and getting worried about The Pale King

Chapter 22 of David Foster Wallace's novel "The Pale King." Huh? Are you kidding me? This chapter is about a hundred pages (most of the chapters are about the length of short stories, but some are a page or two only), all in the voice - as if recorded for some kind of documentary project on the IRS circa 1980 - of an IRS auditor who, at least in the first 50 pages or so, describes his very mundane youth, his wasted college years, his occasional indulgences in "recreational drugs" - and guess what, that's as far as I got with this chapter. (Hoping it's an aberration, I abandoned it and skipped ahead to chapter 23; we'll see.) But what's the point here? DFW seems to be quite intentionally taking on the theme of boredom and tedium - writing a very long novel about probably the most deadening bureaucracy in the U.S., and presenting it to us - at least in some chapters - through unrelieved boredome and banality. You've heard of the banality of evil (Hannah Arendt's amazingly astute characterization of the Eichmann trial, in her New Yorker coverage) - in this is the evil of banality. DFW seems to be hoping that in confronting us with long and tedious chapters narrated in prose that aptly (I guess) captures the way somewhat enervated and nonintrospective government workers might speak to one another - that these scenes and moments will accrue into a great, devastating portrait of the monster at the heart of American society and culture. Or am I overstating this? I'll be charitable and say that, noting that The Pale King is a posthumous novel left unfinished, DFW would have ditched some of these sections, or at least cut them - each one is a unique attempt to get at some aspect of this system, which fascinates him for some reason. But maybe I'm wrong. It's sadly possible that DFW knew he was getting lost in his material, that he was pursuing a chimera down a long and tortuous path and there was no way back. I'm hoping for the best in The Pale King, but nearing the half-way point (200+ pages) I'm really concerned that DFW is never going to pull the strands of this novel together. Scenes, moments are OK - but readers do like plot, and character - at least this reader does
