The Meghan Markle and Former-Prince Harry interview aired last night over here, and a few hours ago in the UK. While it might sound to outsiders that The Royals live a fairytale existence, it sounds like it's closer to being prisoners. They are unable to do what they want or go where they want. Everything they do is scrutinized.
And, if that were all there was, then I'm sure they would still be members of the royal family, living in England, instead of living in Los Angeles. It became abundantly clear what a double-standard there was for treatment of Meghan vs. Kate, specifically.
Here's an article that compares the top 20 glaring differences. Here's one example:
Kate: "Bumping along nicely! The Duchess was seen placing a protective hand on her tummy as she exited the event." Daily Mail: March 22, 2018
Meghan: "Personally, I find the cradling a bit like those signs in the back of cars: Baby on Board. Virtue signaling, as though the rest of us barren harridans deserve to burn alive in our cars." Daily Mail: Jan. 26, 2019
I didn't realize until yesterday that the tabloids in Britain have a partnership with the royal family: the royals give them access, and the tabloids give them publicity. The fact that the tabloids very clearly attacked Meghan for things that they praised Kate for, and the royal family did nothing about it, explains everything you need to know about why they left.
