They get good educations, for the most part. And unless a real ditz, they can make a decent, if not privileged living. Freddy Windsor, for example tried his hand at modeling, entertainment and last I heard banking [maybe not the best choice there] And he is not even duke, royal or otherwise. Just being from those classes gets them on boards, whether or not the actually do anything. I know a son of a very prominent duke [non-royal] who is a total waste of time when it comes to career, but he does not care, idle rich is his lifestyle but he is on several boards. Just his name opens doors. Perhaps not as much as before, but class does still count- way too much in many cases. By the way, I like him a lot, we have been friends for years.
