I think it's harder to get away from a rich abusive man vs poor abusive man. Because a rich abusive man can pay for a lot of things to make a woman's life miserable vs a man who can't afford anything. But, abuse is definitely not about the money. Plenty of women on mumsnet who are in abusive relationships for years with a man who doesn't work.
Poor girl, I saw the footage, it's heartbreaking. I can't even imagine how hard it was for her. I understand why she took the money instead of a trial. Only because she was with him, it doesn't mean she actually had any kind of money in her own bank account.
The fact that he paid a settlement is proof he was afraid to lose the trial. Otherwise, why would he pay her? The video is proof he was very violent.
