I read it the opposite way: that Huxley was using consumption as one example of how modern society substitutes happiness for purpose (religion). Other examples being safety, sexual freedom, and drug use.
I remember reading it as something like that, how everything was about consumerism and happiness replacing religion and morals. In fact religion and morals ended up looking like some strange creature that no one could understand in the end and became like some lost civilization to poke at behind glass or some sort of zoo. I recall the ending the most striking as I'd say the character went to the extremes of religion in contrast to his culture, like a crazy monk going off to try and whip himself into shape to feel something that no longer existed in his culture therefore becoming their next form of mindless entertainment. Though I never took a class on this I think it would likely have been interesting. I know this book was written in opposite of 1984 but I feel it's messaging wasn't as clear. 1984 had two ending, this book, I'm not sure but it feels sort more hopeful in some weird way to me at least that was how I remember.
