Once she vomits out what's been in her heart all this time then she would leave only to never return again. But if she was provoked she would become the biggest hurdle in her life.
She knew how these rich people were. Once they do not like a person they destroy them until they are satisfied. She didn't have enough money to fight her but if she had it, she wouldn't waste them on the likes of her. Instead, she could withhold herself until she bashes her out to her heart's content.
Voicing for herself would only make her the target of her hatred and she would do odd things to just get back at her. That was another reason why she hated these rich people, they would use their money to play with innocent lives.
