I would think he should be able to at least write a decent paper -- if he has to have someone do that for him, they would be better off giving them the job. Although he was an officer I think his only transferrable skill is helicopter pilot, although he would have taken plenty of classes to get his rank. William was able to get a job at that after leaving the military -- flying an air ambulance until 3 years ago.
Personally, I'm seeing an issue with how a lot of their future income seems to be coming from non-profits, all based in the US but with operations all over the place. There is one that does eco-tours in the UK, which really ought to be a for-profit company since the tours will not be free. I'm only thinking on this because here in Canada we had a huge problem with a big non-profit that turned out to be just a cash cow for the brothers who run it. Administrative costs were through the roof, and they were renting office space from another non-profit they run that owns the building. Sometimes people set things up this way just to avoid paying corporate taxes, but the guaranteed income from donations is mighty tempting.
I don't see how either of them is qualified to run a lot of these non-profits either -- nobody knows everything about everything, but they have a lot of staff so I guess their job is just to sit back and count the money.
