There can be no harmony with Meghan as everything is a competition. She is always On, always performing, always masking.
Let's not forget her dad won the lotto and that paid for the private school. Meghan would have been one of the less well off attendees, less travelled, no ponies etc. Just enough to pay for the school. Afterschool she hung around the low brow (hyper objectified) set of married with children.
Archibald Harrison, is the Archy-archetype and Harry s son. Lillibet Diana is the princess, where Meghan has personally failed, she can work on Lilly to be the American Princess. The strategising continues.
It's a pity they couldn't maintain dignity, if they had, they could be making hygge jam and tea with flower petals within the comfort of the Royal Machine. But Meghan can only cope in Meghanland, she doesn't fit into any other institution.
(Despite the above, the Susexes are being more responsible than each set of their own parents were, at a similar stage in their lives.)
