Of course the RF, and in particular Charles, would have set them up. He might have been irrelevant to the monarchy but over the years they did everything in their means to help him find an independent life and something worthwhile to do
They supported him obviously because he was part of the institution. As they support all working royals. You are sure not saying they supported him in order to become independent of them? The whole point is that no one expected him to want to be independent, so they supported him from within the institution to be in the institution.
The army, Invictus games, all of it was aided and abetted by the royal family, as well as all the attempts to hide his drunken exploits as a youth. They wanted him to have a good life. He was the grandson and son; he was given assistance in all walks of life. He turned down several opportunities offered. I don't have the receipts to hand but that's well known. He was definitely not hung out to dry, neither before nor after Meghan.
As above. He did not enter the army so that he could be independent, he did it because they all do army service of some kind, some more successfully than others. He left the army because he became frustrated with not being in active service. Can you not imagine how awful it must have been not to be able to do the one thing he found he was actually good at, because the media were threatening to reveal his location and endanger both him and his fellow soldiers? He retired in the end because he was unhappy with a desk job.
As for Invictus, it was Harry's initiative but it started as a family gig, under the Royal Foundation.
But he cut himself off and was told there is no half in/half out. Charles gave him loads of money to help in the beginning, certainly enough to set up a more modest lifestyle if he so wanted, a lifestyle most of us could only dream of.
This was a spectacular failure of imagination, because with enough patience and goodwill on both sides, I believe that a half way house could have been found that didn't require them to make lots of money, and that would have allowed the relationships to be amicable. It all went tits up. I saw an interview with Valentine Low, who is highly regarded here, who said the whole thing was handled badly on both sides. I agree with that.
Further, Charles gave him and William a share of about 4 million pounds I believe. As has been reported widely, Harry is a target for Al Quaida and other loonies because of his military service. His wife and children are also targets from racists, one or two of whom have been convicted in the UK for death threats. They need security, and a share of 4 million from Charles was not going to cut it.
Some have this fantasy that H and M could have lived a simple ordinary life in a little house in England. The reality is that them just leaving has been enough to bring them a tidal wave of hate because it has been seen as a rejection and betrayal of a Royal Family and monarchy that people hold dear without thinking about what living these lives, ordered from birth, actually do to those who actually have to live them.
And, as he has said eloquently, he inherited the risk.
There is no life he could have lived that meant he was not the son of the King, a soldier who served in Afghanistan, who married a biracial woman subject to racial hatred and death threats. Even if the calls to have their titles removed succeed, he will remain with the risk he was born with, and that his army service exarcebated, and money that might be enough to you and me would barely cover his security.
Still waiting for that apology!
