Wilhelm might be clueless about social norms sometimes, sure, but he's always tried to make others feel included. Maybe it's partly because he's supposed to know how to with being a prince, or maybe it's because being a prince makes him feel non-included, but he tries.
It's through soft sentences, spoken with a laugh or distant interest, so they don't bring attention to himself or the situation itself, but he subtly tries to include people. We see him doing it the first time really in Season 1, at Parents' Day lunch, where he reassures Linda saying she doesn't know anyone with a simple sentence along the lines of "Well now you do." Right after that, he reassure Felice, when she's feeling clearly insecure, telling her he thinks she's perfect, not taking in account the next move of the girl (because he was clueless about the fact that Felice had a crush for him, yes, but also it's just considerate). Then way later, in Season 3, when they're joined by Rosh&Ayub&co at their camping trip, they're talking about the summer holidays. He knows how rare it is for Simon etc. to go travel around, since Simon has lectured him about his privileges over and over again when Wilhelm didn't take them into consideration. He senses Rosh's uneasiness about the fact that she said she was going to work that summer and that the Hillis directly went on with 'You've never been to the US?' and brag after brag over their fancy, all-inclusive holidays around the world as if money was a given. He sees it, and means well when he says he's also going to work that summer. Simon fairly tells him later that it's nowhere near what Rosh is doing, but at that moment it was clear to me that Wilhelm was just, albeit very cluelessly, trying to make Rosh feel included.
There's a few other moments like that scattered through the show, and I wish people took notice of it more, because it is such an important quirk of Wilhelm's personality. (Cluelessly considerate.) Of course it's an issue in some way, because he doesn't realize some very important details that make the situations so different, but he tries.
