Query: essential insight for modern times

The targeted corruption of our language by people with axes to grind, and the disappearance of free speech in their wake is a fearful blight, and she lays it all out. (Niggardly is a perfectly fine old word meaning stingy, but is forbidden in schools because it sounds as if it might mean something else.) The book does make the same points over and over again, as others have noted, but they may have to be hammered home. The only matter on which I disagree with her is that she has some hope for the future, while I have lost mine. The downhill road rarely turns up. Gresham's law in economics notes that if good money and bad money are in circulation at the same time, the bad money will drive the good money out of circulation. In this case the deliberately corrupted meanings of words are the bad money. Read it and weep, and then applaud her for the courage to say it.
