Inside the World's Largest Science Experiment

So the LHC literally has only proved something we already use in math and predictions. And That's it? I know it allowed tech advancing in detectors that are good but compared to USA older collider that found most of these particles it really hadn't profited much.
Maybe or did teach us what doesn't happen more than what does happen.
The American particle physicist forefathers were correct in thinking it would take much much bigger collider than this to take the next steps.
But for me, I think it'stooo many physicists giving up on long-held there's in search of there own bias and making math do whatever they want instead of letting the evidence dictate the math. Like any language, you can manipulate it to mean whatever you want. 
We are getting always from our best theory trying to find particles for everything like a gravaton controlling the force of gravity. It goes against everything went learned.string theory isn't leading the community in the right way.
