Funny because when considering SD, they made it sound like that problem is still ongoing since Naruto must become Hokage to fix it.
Oh well.
How can that be considered true reform from the inside of the family when you're needing an outside political entity to impose these changes to the system? It doesn't change the hearts and minds of the clan members or make them want to enact new policies for the benefit of their own people. For that matter - isn't it undermining the authority of the clan leaders when you have outsiders meddling in their affairs? I'm guessing Kishi didn't think this through when he first made Naruto give that promise to Neji.
