What is an example of a short story with a moral lesson?

The Necklace- against avarice and social-climbing with a gimmick- impled anti-materialism. The overcoat ( O. Henry-nice rewrite by Superman writers in l950"s) is a similar tale of false confidence in money- turns out to be Bank of Richmond- circa l863!- there are weird ( Trapped) short stories where the lead character or one of the characters is in dire straits by accident- being trapped in a bank vault or something like this. I can remember a cartoon ( yes) a cartoon that dealt with the abandonment theme and an ( Evil) truancy or juvenile police officer- it gave me the Willies! The shock of the child being abandonded in a strange officer buiilding basement- well it was in the shockumentary category- other tales have moral or ( human condition- is it right or wrong) angle of presentation. Some of this stuff is intended to moralize or at least shock the reader into some Moral solution-If people were honest- nobody would be fatally trapped in a prison fire int he keep-locked ward as was Zelda Fitzgerald.. it happens.
