I have to say, as a Brit living in America for almost 20 years now, Highgrove won't even be on Meghan's radar, let alone be her competition. I keep banging on about it, but she really is not interested in the UK. Nothing she has said or done since she married Harry would indicate that she is, and all her words and actions since she married him show that she cares only for a tiny subset of Californian society. (She put her toe in the water re Washington and got laughed out of town.) It's Harry who goes back; Harry who has maintained links with UK charities; Harry who is suing the press there; all the links to the UK are his. She doesn't look back. If her kids could have Monegasque titles, or Spanish titles, she would be acting exactly the same way. She's not intelligent enough, cultured enough, wise enough, experienced enough to be able to cope with more than the little subset of Californian society that she lived in/around for her first 35 years. She hasn't got what it takes, she knows it, and it's part of the reason she can so easily turn her back on the UK. She's out of her depth.
I think it's difficult to make the cultural move, mentally. There's an ENORMOUS cultural difference between the UK and pretty much anywhere in the US. There's an enormous cultural gap between different points of the American compass let alone anywhere abroad! I know it took me many years before I accepted I'd left home and had become American (by my experience, Harry has many years still to go before he can let go, and I'm not even a Prince of the realm). I enjoy MN because it keeps me in touch with normal people in the UK. All of you would have been the people I would have seen at the school gates, worked with, lived next door to, everything. But from over here, you're very far away, your culture is very different and I can go days and days and days without sparing a thought for the UK. And I was brought up there! You don't even register for Meghan. She's not interested, she doesn't care. Or rather, she only cares to the extent it might impact her, well or badly, in California.
For Meghan, her short stint in the UK was probably like a really unhappy gap year that got prolonged because she got married to a Brit. She's in no way British; she isn't even mid-western or an east-coaster. She's California, through and through. Her market is people like her, in California. And now that she's bagged Harry, she thinks her circle is EVEN smaller, even more elite, even more exclusive. She 100% sees herself in the Gwyneth realm (although the rest of that world pegs her about as high as Blake Lively on a good day, but with a poorer reputation and a not-as-helpful husband in tow). She will find all this stuff about the Trussell Trust annoying, irritating, a fly in the ointment. She will feel dragged down and victimised that whatever she tries to do, some Brit somewhere will mock her and that mockery will make its way onto the internet and infect her in Montecito.
