Actually this is a blueprint example of toxic masculinity and how it hurts both women AND men. It's based on a pre 1960 idea of marriage and partnership, where a man has to keep his wife happy (mainly by buying her things and not contradict her) so she won't mope and nag to an extent it's poisoning his life. To believe this system is working to women's advantage is very short-sighted. It's very well explained here:

Given how you apparently feel personally attacked by me using the words "toxic masculinity" it's extra creepy how you would have a "favorite knife" to train self defense.
