First off let me say that I am not interested in discussing whether the LHC is a worth while project. I believe human beings are curious by nature and that learning new things to satisfy that curiosity fulfills a human need just as real as any other. What I am interested in is discussing applications of new physics discovered at the LHC (or other high energy collider) that would effect the average person. If known physics is enough to make predictions at energy levels below 5 Tev then it seems like any technology which would require the new physics to engineer would operate at higher energy levels. I have a hard time imagining commercial applications for 5+ Tev accelerators. So I guess the essence of my question is "what could possibly be learned at the LHC or similar facility that could be used to solve problems or improve quality of life for a large number of people, excluding the psychological benefit of satisfied curiosity?"
