The profoundest obstacle to Socialism is socialisms: families. Marx and Engles understood this clearly. It was with good reason that they advocated for the abolition of the family. It was with good reason that they attacked inheritance rights. Inheritance rights are "a basic mechanism of class stratification." "Once you start putting away money for your children," wrote Will Durant, "you are halfway to becoming a conservative." Economic inequality is inevitable for so long as, and to the extent that, parents privilege their own children above the children of strangers.
