As a Jew you're about as far away from "Underacheivement as a group Defense Mechanism" as it's possible to get. The history of the world is filled with stories of people who have lost their way, their identity and become bland (not least the ten tribes of the north, if you buy into that).

Sometimes one half of a married couple will do it so they can secure education for their child. See _Chinese Whispers: The True Story Behind Britain's Hidden Army of Labour (Paperback)_, Pai, 2008.
