Maybe this show the role they envision for their family i.e. a mini royalty that can do 'royal' things on a proxy basis for US citizens?
This is what H has been brought up to do. To him this would be a natural move. I can genuinely believe this was what he was thinking of with the 50% in the RF. Invictus, Sentebale, military events, official events.
In someways this is also what appealed to M. It’s worthy, high profile, and it adds cachet. What she clearly did not want was the drudgery of most royal duties.
If they had just said we want to be part time working royals, only do the bits they fancy for most people that would be fine. The problem was they (M) wanted the prestige events and expected senior royals to defer and do all the drudgery.
The really problematic part was, and still is, the 50% out of the RF. Decades ago the Edinburgh’s showed it didn’t work if it is media based.
The Duke of Gloucester successfully managed it, being an architect. The difference is being an accountant, lawyer, architect etc. are, in media terms, low profile. Harry, Andrew and others made it work with military service.
It’s wanting to work in commercial media that’s the issue. Had M continued as an actress that might have worked. It’s the commercialisation of the Sussex brand that is the issue. The desire to be a celebrity and all that brings is just not comparable with royalty.
