Q: The crowning process now over and the principality’s leader now back reigning over Little Mountain makes me want to ask, how will this recent step affect the world’s economy, the USA’s economy or that of Great Britain?
C: It shall not.
Q: Why did Harry go along with his wife’s ambitions?
C: Contemplating the rest of his life as a royal utterly depressed him. His wife's life offered an escape valve.
Q: Did he really feel like a spare? Will his father’s now official placement upon the throne change him or anything material?
C: Yes; no. What is revealed and emerges might seem and will likely be cast as a change, however it will be no more than what was always there, becoming publicly known.
Q: How badly does he miss home?
C: Very much but nostalgia will not overcome how much Harry dreads the prospect of returning to a life of mental drudgery, dullness and boredom on top of feeling expendable, unaccomplished and unnecessary.
Q: Did he always feel this way?
C: Beginning as a teenager yes, increasingly but this was solved and delayed by his years in the British Army.
Q: Can the world safely forget about him?
C: Yes and no, both. Yes, because if he were to become much less well known or famous, this would have no consequences for The United Kingdom but no because his life plan, the decision solely up to him and not yet made, is to become more involved in policy and governing of the United Kingdom after his father passes on. The difficulties with his older brother will resolve, privately then publicly.
