„Gaps in children’s skills based on family background appear long before most children enter preschool and kindergarten, which underscores the relevance of the home environment. Across disciplines, hundreds of studies have documented differences in the way advantaged and disadvantaged parents raise their children and have shown that these differences matter for children’s development and adult success.“
