Supplement

Supplement means "something added to complete a thing, supply a deficiency, or reinforce or extend a whole." If this definition is linked with Bernays' statement then I think there is definitely a salvageable notion here. Women supplement men, just like men supplement women, women supplement women, and men supplement men. I think the key to rewording this for a 21st century world would be to make this statement equal for both sexes; "Women and men supplement each other in both private and public life by working together to create a product which is a result of a combined effort." I believe that men offer insight that women cannot and visa versa because we are natually different. If the statement needs to be more broad then it could be reworded by simply saying "individuals" or "humans" but the reality is that we, as a society, continuously work together to complete a "thing" regardless of what that "thing" is.
