For the most part I agree, but there is one area that I would a have a decent amount more sympathy for him, and that's if the offer sheet rumours were true and somewhere in the 12 x 7 range. It would lend credence to his ask, and at his age the reality of "the place you want to work" and "place that will pay you the most" not being the same might be a harsh and frustrating lesson.
At a certain point I think all reasonable valuable employees come to understand that they could make more money elsewhere. Might require living where they don't want to, hours they don't want, a worse work environment, a company they don't believe in, more responsibility, etc. We all know the tradeoffs, and that we all have to make those choices. With that knowledge it becomes really easy to look at someone that refuses to accept the tradeoffs and wants to have have their cake and eat it too as spoiled, immature, entitled... but then we remember we're talking about a 21 year old that's led a pretty charmed life, and this might be the 1st time they're facing it.
