"Not needed"-- that is one of the tragic experiences of the young girl in the well-to-do family.

To save herself, to meet the truth of her day which has taken hold of her, she must seek a productive place; that is, leave home, seek work.

If she has some special talent, knows what she wants to do, she is fortunate indeed.

With the majority it is work, something to do, a place where they can be independently productive, that is sought.
The girl of the family in moderate circumstances is no better off.

She must contribute in some way, and there is no scientific management in her home--no study of ways and means which enables her to contribute and remain at home.
