While one job in the city might attract 100 applicants, one job in a small community of 100 people total might attract two applicants. This forces rural employers to be less choosy about who they hire, and enables applicants to be less special as they do not need to stand out from the crowd in the same way their big city counterparts need to.
While I am not about to suggest that college is only for building careers, I find a large segment of students treat it as nothing more. When you remove the feeling that you need a college degree to get a job, as is the case for many who look for work in rural areas, that removes the reason why many want to attain a degree.
