Because If they have wealth and they do something wrong to someone,penalizing them the same way you would to someone that doesn't have much would not hurt them much because they are rich.
I don't think you understand what a tort is. Maybe you should google it. No one is found guilty or innocent in a tort case. The kind of legal case involving Bill O'Reilly or anyone else concerning sexual harassment is a tort. No where in the United States is it a crime to coment on womans appearance or ask another person for sex.
In a tort, the plaintiff must show the defendant had a duty, breached the duty, that caused an injury to the plaintiff. That injury to the plaintiff is going to be quantified into a monetary value. The monetary value of the injury to the plaintiff is the same regardless of the wealth of the defendant.
Now on to punitive damages. Some jurisdictions allow for it, many don't. In all cases, compensation for the injury must be determined first. In a tort, the fact finder only needs to find a preponderance of the evidence to make a judgement. Many jurisdictions that allow for punitive awards, require a higher standard of proof from the evidence. Even if the case involves suche behavior that warrants punitive damages, the wealth of the defendant should not matter.
