This is such an absurd comment I have to counter it.
The library near me is wonderful, and my wife regularly goes there just because of how peaceful it is and how broad their e-book collection is for her bus rides. I'm in a normal no-name township, nothing particularly wealthy. Same goes for the library where I grew up, and from visits back, it's in about the same state. Volunteer work there was integral to my growing up, and accessibility to the books there was 100% of the reason I became such an avid reader.
Just because you don't like libraries, and you may have seen some bad ones, doesn't mean you should seek to remove one of the remaining bastions of government services that purely serve to better the quality of life accessible to all. (I'd cite PBS as well)
I'd say the same about museums. To abscond from a public duty to educate and provide information, we religate ourselves to the unfortunately trend of a citizenship lacking in critical thinking and inquisitiveness.
If govt spending is such a key issue, it's mind-boggling that one would focus on such trivial non-%'s as opposed to the largest allocations, of which there are MANY well-discussed inefficiencies.
