Haven't read all the posts, but jealosy isn't the issue.
The fact is, if someone put up the cash, all the guy had to worry about was concentrating on the course. OK, you need a minimum level of brainpower (and a good schooling goes a long way to help), but that's all. Age is irrelevant. A much younger kid could do it.
Then you have to get a job. Helped by someone with influence, again no big deal. Age irrelevant once again, then.
But this is the revealing comment.....
As first officer you do pretty much the same as the captain
Now that
does sound like a guy who's too young.
I guess that in Titan the Cabin Crew make all the decisions, based upon their years of experience.
Love to get him in the simulator with a raw F/O and see how much he'd manage to do 'just the same as a Captain'.
