Her skills DID NOT MATTER. She was a woman, and was confined to the pink ghetto of available female jobs. She could get to the top of a profession, but it was a low paying profession. She would never, ever have been able to be the bank president. If there was a board of directors, then they would not have allowed it. If she was an heiress, or otherwise had enough money to buy the bank, she would not have been taken seriously by other banks, or other businesses. Nobody would have put money in her bank, or asked her bank for a loan. If she had inherited the bank somehow, she would have found it necessary to hire a man, any man, to be at least a figurehead. She was a WOMAN, no matter how she dressed and groomed and acted, and in that time, she was only able to get hired in a few lowpaying jobs. It was OK for her to act as prez when Drysdale was unavailable, because everyone understood that she was just a temporary placeholder.
The reasons women went to college in that time was because of a genuine love of knowledge, to get the skills that the wife of a successful man might need (being fluent in a couple of languages is a great skill for the wife of a diplomat, for instance), or to catch a man who had a bright future. It might be some combination of the three. I don’t think that teachers needed college degrees back then, just a high school diploma, and possibly going on to normal school, unless they were themselves college teachers. Nurses and secretaries tended to go to trade schools to learn their skills. Usually, women’s colleges had a “brother” college for men, or rather, men’s colleges frequently had “sister” colleges, and the women who attended these colleges were regarded as a pool of dates and possibly wives for the guys who attended the brother colleges.
Miss Jane was a highly intelligent woman of her day, but she was severely constrained by the fact that she was a woman…and even worse, she was an unattractive woman. Being unattractive and not making even token gestures to increase one’s attractiveness was an unforgivable sin in a woman in that day.
In much the same way, a black man could not have aspired to a well-paying, highly respected job back then, with a few exceptions. Being an entertainer or a preacher could bring a black man, or a woman of any color, fame and fortune. Otherwise, don’t whine about your lack of opportunities, and keep pushing that mop, that’s all you’re good for.
