I'm looking for a word that describes a sort of 'Lucius Malfoy' character (from Harry Potter); someone who has a wealthy and respectable facade that disguises a criminal or prejudiced interior. It doesn't have to necessarily be an adjective; a noun would also work. Thanks!
I don't know that there's a specific word for this yet. But it's not uncommon for the name of a person to become a word that refers to something they're famously associated with. Examples are boycott, chauvinist, and gerrymander.
So at the risk of angering about half the US population, I suggest that "Trump" could become a word for what you describe. His public persona is a rich and glamorous businessman, but he's associated with many crooked business dealings (not even counting possible involvement in the January 6 insurrection) and there are credible accounts that he has inflated his net worth on many occasions (while also deflating the values of some of his properties to avoid taxes).
