Thanks for finding this and posting it. I notice Ms. Shinn is still ignoring marriage. I cannot emphasise it enough. Marriage and a strong family culture is number 1, 2 and 3 on the list of priorities if you want to decrease any wealth gaps.
I bet the combination of marrying and staying married, plus eating dinner as a family will out do the entire list. Family is the foundation of any civilization of note. Destroy that and you destroy your civilization.
