Billionaire's should arise the MOST suspicion, using that logic though, right? I think so-- never trust the billionaire's man. "Behind every great fortune is a great crime, or something like that." - Batman, probably.
ETA because I googled it and AI did the work for me:
“Behind every great fortune there is a great crime” is a quote often attributed to French novelist Honoré de Balzac. However, the quote may have originated from a paraphrase in The Oil Barons: Men of Greed and Grandeur by Richard O'Connor.
Explanation
The quote suggests that all wealthy people have achieved their success through illegal or unethical means. However, many people achieve wealth through hard work, innovation, and ethical business practices.
Origin
The full quote from Balzac is, “Le secret des grandes fortunes sans cause apparente est un crime oublié, parce qu'il a été proprement fait”. This translates to “The secret of a great success for which you are at a loss to account is a crime that has never been found out, because it was properly executed”.
Appearance in other works
The quote appears in Mario Puzo's 1969 novel The Godfather, which tells the story of a Mafia family.
