> A disabled lady thought saving some of her disability was the responsible thing to do, despite further impoverishing herself, once she built up some savings she was prosecuted for fraudently claiming benefits while having savings.

I don't know the specific case you're referencing, and it's possible that they were charged with fraud in relation to a benefit which does come with a savings/income cap. However, the two main disability-related benefits in the UK (Disability Living Allowance and Personal Independence Payment) are paid regardless of personal wealth. I don't disagree with the general gist of your comment, and as I say it's likely that the person was claiming additional benefits where your assets are taken into account.
