I have a history MA and have done tons of research on social/cultural history, which is my specialty.
They were repressed by the constraints of society. It was a different time and place. Women born into the upper classes were expected to get married and keep house, not become Broadway actresses or models or anything like that. It would have been disgraceful. And what society thought of you was very important to them-remember, they were 'upper crust'.
They also probably had no idea how to fend for themselves. They were waited on and never had to do anything for themselves.
Keep in mind the country they lived in at the time in which they lived in it wasn't so 'free' as you make it out to be. (Still wonder if it is.) Women, in particular, have had very few choices and opportunities. And being born into wealth comes with burdens, as their stories clearly illustrate.
