The Major Cause of Rising Inequality is Not What You Think It Is
Income inequality is widely used to castigate capitalism, decry free markets, and justify redistributive policies. Yet there's overwhelming evidence that the main causes of increasing economic inequality in America is not what you might think. According to studies:
• 41% of the economic inequality created between 1976-2000 was the result of the increase in single-parent households. 
• The poverty rate would be 25% lower if today's family structure resembled that of 1970. 
• Communities with a high percentage of single-parent families are less likely to experience upward mobility. 
• Even children in high-income households who experienced family breakups don't fare as well as their two-parent-family peers. 
• More than 20% of children in single-parent families live in poverty long-term, compared with 2% of those raised in two-parent families. 
In other words, the dramatic increase in single parent families has increased poverty in a large number of households and made inequality worse.
