Scientific research has a very high turnaround time. If you want to find out what you're profiting from now, look back nearly a century, when Einstein theorized about simulated emission of photons (laser). Or (more parallel to the LHC), the early particle accelerators, which taught us about the insides of heavy elements and let us construct nuclear power plants etc.

Generally speaking, by the time you can easily see the practical benefit of some piece of research, it's no longer science; it's engineering. Science necessarily does not bring practical benefits for long periods of time.

Edit to clarify wording and add: a pity up-vote for you - that was a good and fair question.
