Scammer philosophy is interesting: "People are stupid. Whoever falls for stupid ideas, tricks, etc. should be punished." (In the comments
here.)
In the Cinderella book
Ella Enchanted, Ella talks to her father and an elderly suitor about punishments for robbery. Ella's father believes in harsh punishment, while the suitor believes in mercy.
Ella knows her father is an unscrupulous merchant so she asks him if it's still theft when someone is
tricked out of their money or possessions. He replies no, it's not the same. If people aren't smart enough to hold onto their possessions, they don't deserve them.
Ella suggests that if a man doesn't have enough security to protect his home, he could also be accused of not being able to hold onto his possessions, and therefore doesn't deserve them.
Her father concedes the point.
