But as @IcedPurple wrote
Meghan was granted prestigious and potentially glamorous patronages such as the National Theatre. They had big tours in Australia and other countries. Meghan were custom couture outfits, paid for by others. They got to hang out with Heads of State and A listers.
In fact, they did very little of the 'opening factories in Hull' stuff. And even the Queen and now the King do plenty of unglamorous work. I would say that as 'spares' they had more opportunity to shape their role than William and Kate, for whom expectations would be more rigid. They had an amazing deal, but were too full of hubris to realise it. And now they're hawking jam and plugging a corporate coaching app for a living.
I just can’t get my head around that she was handed all the above on a golden platter plus Frogmore and they were also apparently offered a country estate, staff at their beck and call, I could go on listing the things that were handed to them, they could have had a holiday home in Montecito if they had wanted, they would have been royal international jet setters! Yet none of it was enough as they wouldn’t be as important as William and Kate.
