I can’t remember the manga it was from, but it was a Villainess wrecking the Heroine’s “oh, the Crown Prince is so alone” with:
“And royalty is amply recompensed for their life of responsibility and duty with luxury and education to match. If he doesn’t want the burden, then all he has to do is abdicate unless he wants the riches without the work. To stand at the top, whether of a state or a company, means loneliness. Who would follow a leader that bemoans their cushy life?”
