She says young people 'today' don't know who they are, and have lost their links with the past. It should be the role of monarchy to help keep peoples' connection to the past. She refers to her being unsettled at the beginning of her marriage until her first child was born.
I read that as an interview which, on the face of it, is in support of monarchy and its role in the world, but in fact is revealing that she knows the occult secrets of the origins of humanity because of her position and she wants to start sharing that information publicly. She's signalling to outsiders that they don't realise who they are and what their real role is.
If she was developing an instinct to reveal to others the knowledge she had acquired, that would certainly not have been good for her health. Especially as she was no doubt aware of the Satanic ritual elements, which no doubt offended her sense of humanity as it did Diana's, and probably Charlene's (below). Did they decide to 'take her out' before she could begin any major revelations to the world of the goings-on on the 'inside'?
The next video shows her father stood as a Democrat, and her uncle was a Pullitzer prize winner. The picture goes strange after ten minutes, but you can listen in. Clearly a person of high intelligence, who rose too high for those who sought to control her.
