None of what you say in your post is true regarding Meghan, although there are probably tabloids trying to push that narrative.
In fact, Harry & Meghan rented a converted barn in the Cotswolds until someone leaked the whereabouts to paps and tabloids, and the property was harmfully intruded upon. Meghan & Harry never had any interest in an overly grand royal lifestyle with a huge staff. Where the Sussexes live now is a wonderful property, but it's more west coast Garden of Eden, than it is snooty, palatial and frosty upper class. The original owners who built the Montecito property love Italian and French architecture, so they designed the home with those preferences in mind. They raised a happy family there. But the tabloids have only abounded with off-putting tales of the later Russian owner who barely, if ever, lived there and who spent years trying to unload it as an investment property.
In California, H&M have a very comfortable, wealthy lifestyle, but it's not overly grand. It's laid-back and down-to-earth. Meghan is a California girl who loves to work hard, and she also loves giving back to others and lifting up those less privileged than she has worked to become. Her head isn't turned by tiaras and ballgowns. She has a lot more substance and character than some people seem willing or able to acknowledge.
There is an interesting article in
The Spectator (Australia), which observed:
"The royals, and those who surround them, still can’t see what they have jettisoned. It will be on display when Meghan and Harry’s interview with Oprah is broadcast."
