Women was created after man because Hashem “saw” that man needed an “eizer k’negdo”, so she obviously had to be created on a higher spiritual level or how could she be an “eizer k’negdo” and what would have been the purpose of creating her?
But that doesn’t make her “better” than man, which is I think what Joseph was arguing about, because he thinks that women think that. Personally, I don’t know women who think that – I think that most women have inferiority complexes which is why everyone always stresses the ways in which women are on a higher level.
