The Higgs is something we have to spend 7 billion dollars (admittedly a pittance in the grand scheme) just to have the potential to observe it, so surely you can see why I (and many others, I'm sure) might be a bit skeptical about ever having a use for any knowledge we gain about it outside of academia.Similar arguments can be used to suggest that we should rid colleges of literary theory, gender studies, philosophy, sociology, large swaths of psychology and economics, most fine arts, probably half of research-level math, and so on, leaving only the fields that consistently give actionable real world results (basically leaving only the pseudo-vocational fields like CS, education, and engineering, and a very trimmed list of research fields like chemistry, bio, medicine, and the few cherry-picked bits of practical physics that we need so that the other fields can still progress).
We reject these arguments, though, because as a society we value (and fund accordingly) the pursuit of knowledge for its own sake, even in cases where it's highly disputed whether there's any "knowledge" to speak of at all (I won't name names, but that list above...).
Of course, then the matter of cost comes in, and I certainly wouldn't claim that 7 billion is an amount we should shrug our shoulders at, whether information about the Higgs alone is worth that amount of money or not is definitely up for debate...as much as I might like to bitch about how inconclusive, statistically flawed, and poorly conceived most psychology studies are, they're not costing billions of dollars to run.
