Haunty (hi!) The problems facing most of Charlotte Bronte's characters was to avoid sinking into the underclass, a place of danger and privation for single women of that period. Educated women of that time were able to support themselves with few opportunities. Being a governess was one. But that was a restricted kind of life for the types of women that Charlotte wrote about. The governess was a cut above the servant class so was not able to comfortable socialize with other workers in the home. She would be of a lower class than the folks that lived in or visited the home.
The ability to financially sustain themselves inspired all the Bronte sisters to write. Even then, they wrote under assumed names because they felt that their novels would be more acceptable to the public if they had been written by men.
The Bronte sisters struggled to maintain their station in life by teaching and, eventually, writing.
Shoot! There is a long hub in this. You can check out my hub about Charlotte's sister, Emily http://hubpages.com/literature/EmilyBronte-theFree...
