I work at a library, which is one of the frugallest places there is.
From my point of view, libraries are centers for imagination, information, and education, which are all ways that can help people earn more and spend less. Plus, you can get books for free. But at the same time, it saddens me when I see people using the library computers to apply for payday loans, or investigating some get-rich-quick pyramid scheme.
(By the way: whenever someone is checking out a personal finance book, it seems like they have racked up $50 in fines... I always think to myself that I hope the book helps!)
