That movie was made in the 90s, right? I think that culture has shifted some since then and people are less obsessed with brand names. But maybe that obsession has been replaced with looking good on social media?
And yet, what do people remember most about the film? Brad Pitt's shirtless physique during fight scenes. Look up "Tyler Durden Fight Club fitness" on Youtube. Tons of hits. People may conceptually understand that Fight Club is satire, but their actions indicate otherwise. They want to have that kind of body, even though they know it's not going to make them a movie star or a rock god.
Boiler Room on the other hand might have been a worse movie, but it had a low-budget feel about it that at least grounded the characters and story within some sense of reality. I think they were going for the Glengarry Glenross aesthetic.
