The best part is the comment section, it's littered with university professors doing what they do best (erm worst). From the petulant arguments concerning grammar to the boasting about how some have beaten these ghostwriting schemes (unlikely), and they are almost all writing with undertones of self defense. So typically out of touch.
I'd be curious to know how much this dude actually works for his 66 thousand and if he's getting taxed on it. In practical terms it really might not be as little as it first seems.
