I quoted your entire post because it's brilliant. There simply is no comparison between the two women's proceedings.
I agree there is no comparison.
One woman deliberately lied to the Queen - 'Oh no I had nothing to do with the Morton Book' - deliberately lied to the public - 'there were three of us in this marriage' conveniently forgetting the three or four that she added to the marriage and I could go on. She made repeated public announcements through the press and in interviews to discredit her husband and the monarchy in general by association - it was deliberate and calculated to harm the monarchy in general and Charles in particular in their public roles.
She deliberately run down the father of her children in public and to the public.
The other, while indiscreet, was entitled to think that a private place was just that - a private place where the press would respect that privacy. She hurt people yes but it was deliberately in public designed to hurt them and discredit them in the eyes of the public.
Sarah has made mistakes certainly.
As for the divorce settlements - Diana was rewarded for his vicious attack on Charles and there is no question about that. Sarah wasn't rewarded for having an affair and being found out.
The difference was that throughout their married lives the press made Sarah out to be the bad one and Diana the saint and a lot of people have bought into that myth because of her lies and deliberate contortions of the truth for which she was rewarded.
Sure she should have received a decent settlement as the mother of a future King but Sarah is also the mother of princesses and should have received a decent settlement as well rather than the pittance.
As for their respective wealth - the Queen and the Queen Mother were both reported as having to help pay Diana's settlement as Charles couldn't affort to and has been reported a number of times as having been almost wiped out financially by the settlement (over the top to have the husband in that situation when the wife already has a substantial fortune of her own which wasn't also divided and half given to Charles). Sarah got a house, a small annuity, which isn't much even today for a woman whose daughters are princesses, and a paltry 1,000,000 pounds or so in comparison.
She had to earn a living and had to use her association with the RF to do so and that is all she has to use for the future. That she has to rely on handouts from her daughter's trust funds says a lot about how deep she has been affected by the GFC which has wiped out many many people with investments etc.
I don't see her as greedy but as desperate to get out from a hole and fully empathise with her and her situation.
She has been a great mum and a loving friend to Andrew but she has also been the butt of a vicious press campaign since day 1 and frankly I wouldn't be surprised if she did something awful and tried to commit suicide and maybe even succeeds over this. Thankfully it seems as if Andrew had already decided to stand by the mother of his children if the reports I have seen this morning are right and that he 'forgives' her.
