The Gemara in Arakhin 19a quotes Hizkiya, who explains why the value of a man decreases more with age than a woman's value decreases:
אמר חזקיה אמרי אינשי סבא בביתא פאחא בביתא סבתא בביתא סימא בביתא
Ḥizkiya said that people say a popular saying: If there is an elderly man in the home, there is a burden in the home, as he does not help with anything; if there is an elderly woman in the home, there is a treasure in the home,as she assists with various domestic labors.
From what I understand, the Torah's laws are timeless, but I am wondering, would these values need to be readjusted today given that the roles and value-adds of men and women are completely different than they were in those days?
Today, it would seem that it is generally not correct that older men are more of a burden than an older woman, and furthermore, if an older man IS in fact a burden, the woman has the option to divorce him and free herself of the burden, an option that was not available in the times of the Torah.
Do we have any modern halachic discussion on the monetary "values" of people as eras change?
