Well... At the start he is clearly set up in the global. I think the most telling scene is the one where the camera pans around him and he talks about how "things" fulfil him, and has the price-tags underneath the things on the floor.
But it literally makes him sick (His inability to sleep), and he needs some human contact. To cope he goes to those support groups. But even that doesn't help when he realises other depressed/post-modern global sufferers are doing the same thing.
So then he meets Tyler and literally retreats. Compare his old apartment to the place with Tyler. The ideas of masculinity in his new local, the middle children of history speech, and what they now value.
There's also ambiguity at the end as the global spreads the local of fight club.
This is all of the top of my head in half a minute...the movie is literally full of RFTG, just sit down and think about it and itll come.
