"Pathological Altruism"

Well, I haven't read this book yet, but it has been getting plenty of MSM buzz, including from the New York Times.

But I'm confused. Didn't Ayn Rand first make this an issue, oh, around 1943, in The Fountainhead?

And isn't she still being denounced and mocked for it, to this very day?

Why is it that a truth isn't a truth unless it's "discovered" and propagated by a gang of Establishment academics?
