It is not a big stretch to solve this problem. In history, when there was a rabbinic will, there was a Halachic way. Traditional rabbis need to be made aware of that this is a serious injustice and the situation cries out for a solution. There is an element in feminism that is against the family. Feminist's fight for equal pay for for full time workers, but do nothing for part time workers who are mostly women with children.
Some elements say that the family is the cradle of evil.
Such an attitude is against Traditional Judaism. Also there has been a discounting of volunteer work. If it isn't paid for, it isn't worth anything. These sorts of attitudes must be guarded against when incorporating feminist values into Traditional Judaism. Abortion is another issue.
