Additionally, while you're talking about budget in a practical manner, spending money on science to discover science isn't something that people outside of science generally love spending money on. I am nearly certain that part of the hope for people spending that kind of money on the LHC is not only might they discover something amazing but that it might also be practically useful to someone else.
There are other scientific fields that produce much more tangible results that the finite funding could go to. Even something like materials science which could not only produce more useful discoveries but could also make the next collider cheaper.
