That's bloody disgusting, xyfactor. She should have got more than that.
I don't know about compensation in cases like this, but I do have experience of personal injury compensation.
My son was injured at birth by the doctor who delivered him (she was negligent and incompetent). This doctor left my son with a life long disability (erbs palsy)
We fought for compensation for him. It was worked out by deciding what his likely future earnings would have been and how that may be affected, plus the costs of his disability - adaptations, physio, ot, etc etc. plus some for what he went through.
So I know that it is all based on calculations. So, what you do for a living, how much you earn, how much you could earn, how much you stand to lose, does make a difference and does mean that a highly paid professional stands to get more money than someone in a minimum wage job.
