Fair enough. Nevertheless these cushy appointments are nothing other than rewards.
These diplomats get to hobnob with dignitaries and celebrities. They get to live in palaces rent free. They get all sorts of very expensive tchotchkes for free that they can use to adorn their homes. As they walk their guests around their houses they can point out all these items and use them as intros to tall tales they tell about how they tamped down some important diplomatic uproar or provided the key insight to end a political stalemate.
Of course that's just me being human and envious. But I feel I have a right to be as it's all on my tax dollar and it all stinks to heaven as the highest form of hypocrisy.
But better an empty $300 shirt than some well-intentioned peacenik wearing something his boyfriend bought him at J C Penney's.
