The title of The Economist "The traditional family is now the preserve of a minority" seems to say that there is some kind of unjust discrimination going on against the poor and the colored, forbidding them to marry and form stable families. Some kind of apartheid law that preserves the status and advantages of a "traditional family" to a privileged minority.
I dont blame the young journalist framing reality in the PC "discrimination" mold. He grew up in post-Marxist Britain where he was not properly indoctrinated and ignores that the family is an outgrowth of private property. As private property is fast concentrating in a few hands, the institution of family disappears among the property-less masses and becomes restricted to a small minority. Friedrich Engels in "The Origin of the Family":
Reconstructing the past history of the family, we arrive at a primitive stage when unrestricted sexual freedom prevailed within the tribe, every woman belonging equally to every man and every man to every woman.No private property and humans revert to their primitive state. In post-Capitalist America, where the masses own no property, the institution of the family is losing its meaning ("gay marriage") and is disappearing. After a lifetime of ridiculing Engels, it appears that this goyische kopf and not Karl was the real brains behind the Communist Manifesto. Call it serial polyandry or whatever, sexual freedom is almost complete, thus Communist utopia cannot be far away.
