The Ferengi culture being what it is/was really elevates Rom's parenting to s-tier. Pretty much as soon as he realized things could be different and he could break the cycle he does.

And Nog for sure gets the 'Best Son' award. Nog getting Rom to become an engineer lets him shine so bright he gets Leeta which leads him to becoming a Grand Nagus who is willing to try and make the Ferengi a better people.
