Over the years, society has changed but the legislation still exists.

To this day, many women who have been stay at home wives (AK housewife) can get retirement benefits on their husbands when they reach age 62 IF the benefit on the husband is more than twice what they get on their own. A change in legislation sometime in the 1960's or so added husband's benefits. Now the rules are the same for both genders.

Nothing new.
