Prince Harry and Meghan Markle's unhappiness, according to biographer Angela Levin, derives from their need for “revenge” against the Royal Family.

Despite their riches, the royal couple seems to be unhappy with the Royal Family for personal reasons, according to the royal author. She went on to say that Prince Harry seems to agree with the “spitefulness” directed at Buckingham Palace in the wake of the Duchess of Sussex's accusations.

Angela Levin spoke with talkRADIO about Meghan Markle's interview and the relationship between Harry and Meghan.

Here's her reasoning:

It's quite unsettling and troubling that Prince Harry appears to join in with the hatred and savagery aimed towards his family.

I can't believe he's like that; he wasn't like that when I first met him, and all this bile is coming out of both of them despite their new found wealth.

Regardless of the challenges they might have faced in the past, they seem to be unhappy today.

They have no right to feel upset now that they've quit the situation that was causing them so much pain.

They're in a new environment today, and are now in a position to make a bucket load of money.

They live in a lovely home and it's hard to imagine they have something to complain about.

They have one kid and are expecting another, which is such a blessing.

“The thing is that they're absolutely not happy because they want revenge and they're bitter and they want to destroy the people who for some reason has put them where they are.”

Meghan would be almost unknown if she hadn't married Prince Harry; she is now one of the world's most famous and wealthy women.
