As I recall this was a send-up of Ayn Rand novels mostly "Atlas Shrugged"; a novel about the 1990s even though it's supposedly 2023; correctly skewered today's safe-space and identity politics before it had really happened ('if they're the only people who are forbidden to censor hostile speech then they are oppressed' or some such); and was (see previous comment) nostalgic for the '90s before that had become A Thing either (see "The Human Stain"). Then there's the shark called Meisterbrau and all that, though this novel more correctly sits downstream of "Illuminatus!" (whence the submarine, and there's also some sending up of Ayn Rand in that too) and alongside "Infinite Jest" though of course Wallace took up far more space at the time.
