In his book Coming Apart, political/social scientist Charles Murray examined the divorce rates among both the working class (“Fishtown”) and professional (“Belmont”) whites.1
Not only is the educated, professional class staying married, they are marrying each other. A new NBER paper “Marry Your Like: Assortative Mating and Income Inequality” finds that this factor has a major impact on income inequality (see my previous “Inequality and Demographics“).2
Once again, family factors help explain much of the income inequality we see today.
