Prince Harry and Meghan Markle are 2 of the most famous people in the world and a real power couple if there ever was one. After meeting Harry on Instagram and then hitting it off, they got married, which caused a real stir among the British press in part because Meghan is half black.
According to the Netflix documentary they made, they got driven out of the country, not only because of racism, but also because the press thought Meghan was snooty and highfalutin.
So they moved to Canada and tried to make a go of it there, but after still getting hounded by the press, they moved to Santa Barbara, CA where they now live with their 2 small children.
Regardless of how anyone feels about the Monarchy, the main issue is the press and how instrumental it is in forming public opinion, both in Great Britain and here in the US. Whether they're on the left or right, they really don't care what they print or report on TV as long as it sells ads.
As usual, it's all about the money.
