I agree with this and I also think Meghan thought it works hiw Hillswood works.
Take the Kardashian/Jenner family. (BYW I know nothing behind their names so apologies of this doesn’t ring true but it’s hypothetical)…
If they book an event for a time when Kylie for example is going to be pregnant and her husband has left her, she is worth more financially than say her sister Kim who had done nothing of particular note in the last few months. Kylie will get say $100,000 more than Kim for doing the same thing. It’s about clout and relevancy.
Similarly if Chloe has a new boyfriend and is to show him off at an event she’s being paid to be at, she will get more than Kourtney who is bringing the bloke she’s been hitched to for years.
This is the world Meghan has grown up in and understands. She herself pre-Harry did many sponsorships, promos and YouTube videos that she’ll have been bunged a few grand for.
I really think Meghan either thought this is how the RF worked or SHOULD work, that they’d get stipends based on their relevancy and was most horrified when she was told “No, the heir gets the juicier more high profile events ALWAYS and you and Harry will be opening factories in Hull. When William ascends the throne, you won’t even get that as his children will be more relevant than you. That’s the way it will stay and no we will not adopt the Hollywood style framework”.
