This is an interesting analysis of the impact of the LHC, especially in terms of economics.
I think many politicians and the general public do not realize that even for something that is built to study something that appears to be esoteric and no direct and immediate application, there can be immediate benefits socially and economically.
That is why I continue to be surprised and appalled that the US continue to not "care" about their loss in having any kind of high-energy physics particle collider on their soil anymore. This is especially puzzling in light of the fact that other parts of the world are seriously pursuing having such experiments within their borders, even if it is under an international collaboration. Certainly China is pursuing having such facilities, and Japan just announced the start of an electron-positron collider. As far as I'm aware of, Japan is the leading contender for hosting the International Linear Collider (ILC), something that Fermilab has also been pursuing.
But with the devastating budget issues in the US, this is looking to be very bleak. People seem to only see the money being spent on such facilities, without realizing the significant impact not only on the intellectual aspect of it, but the economic impacts, both short-term and long-term. An analysis done in this preprint may not make it to the people who hold the power, but it is certainly there to be seen.
