Catcher in the Rye is the purest and starkest expression of someone's struggle against the environment in which he was brought up. If you didn't have such a struggle (or had it in a very different form), then you're fortunate and your life will probably be better for it, but there will be very little in Catcher for you to relate to. I'll admit that the plot of the book is rather boring, it's just a guy doing some stuff cuz he feels like it. It requires a lot of subtext for it to be meaningful or valuable, which some people lack simply due to different experiences and background. While a lot of people find it a deeply moving or inspiring book, it's definitely a YMMV sort of thing.
