The stress such a position would place on me would far out outweigh any increase in salary. A degree is a gateway to a career path and it must be a path a person is happy with despite whatever opinions others might have of it.
Second, I think the counter article does a good job in pointing out the variety of jobs Library Science Degree holders can pursue. While this may be optimistic, I do think that in the coming years as the economy heals businesses will realize the importance of information and this degree will be in more of a demand.
