What is so cruelly ironic in Lindner statement: "They're not rich and fancy people; just hardworking, honest people who don't really have much but those little homes and a dream of the kind of community they want to raise their children in"?

This describes the Younger family, they are just the same

Explanation:

Linder's statement "They're not rich and fancy people; just hard-working, honest people who don't really have much but those little homes and a dream of the kind of community they want to raise their children in" is exactly the dream the Youngers have of an ideal American dream. Where people work hard live average lives and have a good neighbourhood to raise their kids.

The Youngers were very ambitious and Linder is expressing irony in this statement that implies they are just ordinary
