People paid Hillary because they were bribing the current US Secretary of State, and the Next President of the United States. People don't pay out that kind of money without expecting something in return.
But what do Harry and Meghan have to offer? They have no power or influence, now or in the future. Their is no Return on Investment, here. It is just mealy-mouthed do-goodism.
If these two had half a brain between them they would be out in public, doing work and being seen. Have Meghan home-school kids of healthcare workers, for instance. Or have Harry manfully delivering food and essentials to people stuck in isolation.
They should do something concrete that people can relate to. They should show a little courage and willingness to sacrifice. As formerly pampered royals, that would make an impression.
You mean like this Prince?
And he is worth significantly more than the former royal...
“...no power or influence...”
In their own narcissistic minds they think they have influence. Harry is a “royal”. It won’t work, as you point out, but Meghan thinks she is the next Meryl Streep and plans to have plenty of influence with the rich and famous.
Trust me, she has a Clinton slush fund planned for her foundation.
