We aren't talking about fundamental research here (NIH, NSF, et al) we're talking primarily about students pursuing bachelor's. At least IIUC.

A liberal arts degree is certainly beneficial to the individual's broader understanding of the world, and I certainly would prefer my elected representatives to have a thorough grasp of history and philosophy, but where is the fundamental research that my everyday life depends on?
