The head start from the "accident of birth"

An excellent video and infographic captures how inequality gets baked into your life  from the accident of birth through massive 6000-hour early childhood learning gap,

By the time they reach 6th grade, middle class kids have likely spent 6,000 more hours learning than kids born into poverty. Learning time is a resource that is unequally distributed, and disadvantaged students suffer the consequences. While middle class children learn to read, create, persist, and problem-solve at home and through after-school and summer experiences, parents stressed by poverty are far less likely to be able to ensure those opportunities for their children.

Nicholas Kristof and Sheryl WuDunn have this nice essay on the benefits of early childhood interventions and good parenting on long-term life outcomes of children.
