Unfortunately it's not so simple. If you don't stake the sapling, it will grow unwieldy, if you get my meaning.
Both Harry and to a larger extent Andrew, reveal that there has appeared to be little to no oversight over the educational attainment of the 'more disposable' royals, nor any serious pressure put to bear to contain errant or bad behaviour and ultimately no systematic attempt to develop awareness and appreciation of the grave responsibilities of being a Royal - by extension members of the highest eshchalons of society and ultimately huge benefactors of the good will of the people, which good will they ought to strive to maintain.
No amount of googling as an adult can truly make up for this lack of understanding. Harry lacks the fundamental principles of what being a member of the Monarchy (still relatively close to the throne when one takes into account the position of the wider family members) entails. He just doesn't understand his place, his role, his responsibility. It appears he doesn't even understand how he and his wife's behaviour will influence his children and the importance of shaping their future royal legacy. This is demonstrated by his not even bringing his children to England at major Royal events. Yet he insisted on them having titles!
William by constrast understands all these things.
Clearly effort was put to bear in William's case, and little to none in Harry's.
This is the fault of the late Queen, and the now King Charles. You can say Harry wasn't a good student, but that doesn't explain how he grew up in a Royal Family and yet appears to be entirely ignorant of these basic things, of the import of whom he chose as a wife and how she would fit in. If Meghan became depressed, it is because Harry did not have frank, sober discussions about what being a Royal bride would entail beyond the pretty wedding.
To make it all worse, the palace spun an image of him that wasn't truthful, and let him ride the benefits of that, rather than strive to ensure he had the training necessary to deal with his position in the family. Clearly now we know he experienced mental health difficulties and I doubt all that media spin helped.
