For me the most important in life is dignity as long, there is no indignation to anyone either the parents or the child, taking, using, or spending, money earned by any member of the family is not incorrect.
It entirely depends on the circumstances of the family and the values which are imbibed by the parents, I see no issue as long as there is a requirement to take money from daughters but if there is no immediate need then we can always save daughter's money for some rainy day.
Since females after marrying, stay with the husband for the rest of their lives, it would be a better idea to allow daughter save money, for she will have to fend for her family in case something goes wrong with the marriage, I believe that if the money is not required and can be saved then the parents are safeguarding & securing daughter martial life, in the process of saving.
Replying pointedly to the question, I believe money earned by daughter also has the same value as son, hence giving of money by daughter to parents is fair and correct and there is no indignation about it.
