I think there will be some curiousity about HaM initially, but they can't sustain the salaries they want long term. Past presidents all command millions of dollars on speech tours because of their experiences on the world stage. The role of royalty is different, as are their experiences. I just don't see this being a multiyear type option for them.
People are also tired of being lectured to on the environment by hypocrites. It doesn't matter if they are politicians, scientists who travel the globe and have multiple homes, entertainers, or royalty. If you want to be taken seriously, you need to walk the talk.
On an unrelated note, I wanted to hear the chunga changa song, so I had it on youtube. Hubby remembers it, so now I've had to listen to him singing it all afternoon.
