There is a whole chapter in Roger Kimball's important book: The Fortunes of Permanence on the writings of Friedrich Hayek. In it Kimball, before getting to Hayek's view of "weasel words," offers this:
A weasel was once said to be able to empty an egg without leaving a mark, and "social" is in this sense a "weasel word": a phonetic husk with only an echo of meaning.
Here's a quote from Hayek on the use of "social" followed by a hyphen:
It is..."increasingly turned into an exhortation, a sort of guide-word for rationalistic morals intended to displace traditional morals, and now increasingly supplants the word 'good' as a designation of what is morally right."Kimball goes on:
"Think only of the odious phrase "social justice." What it means in practice, is de facto injustice, since it operates by enlisting the legal machinery of justice in order to support certain predetermined ends."
