Last post on the housewife.
Those who have kids are usually housewives, but Hinata is different from the other moms because unlike them, her daughter is still young. While Ino, Sakura, Karui, Temari, and possibly Ten Ten have children who are already Genin going into Chunin. She still has Himawari who is probably an Academy student so she can't go off and do missions. Another point is that Naruto isn't home to take care of his family because of his Hokage duties, so even if she wanted to work while Himawari was in school, she would have no one to come home to.
I guess the same applies to Sakura too, she probably can't do missions since Sarada has to come home to a "family" and a meal. lol
