This is completely opposite what I experience.The effort it takes to create fluff spontaneously is greater than the effort it takes to convert existing fluff. The converse is much harder- removing pointless time-wasting combats from the adventure changes the difficulty- less combats mean less loot and exp.
I can create fluff all day long. Heck; fluff arises spontaneously during my games on a regular basis. Crunch is what has taken up my prep time from the beginning, and it's fairly plug-and-playable to any campaign. Fluff is much, much harder to re-use, and requires much less time. All IME, of course.
IMO, what you're looking at in 4e is the middle ground. Oldschool products often have much less fluff (look at Tomb of Horrors as an example), and Paizo represents the opposite extreme. (And Earthdawn was probably even higher for lots of its products.)According to who? There is a middle ground. Now if only they'd work in it...
