While some may form rather insular groups by ethnicity, and not assimilate, I prefer to focus on individual motivation, to the degree that is possible when the topic is how children achieve/perform as a whole, by country, and by demographic.

While some may find it difficult to change parental behavior, the qualifications to receive government funding (collected from taxpayers and redistributed) could change, rewarding desired behavior. There is an old saying, "What you reward, you get more of." ***

These choices may detract from, or negatively impact, the level of in-home educational support for these children.
