Well, this book contains a lot -- A LOT -- of interesting material. But the text itself is only 210 pages, which means each little nugget gets very little attention. I would have liked to know more about . . . all of them.
I've listened to and watched David Cay Johnston on NPR and TV, and I greatly respect his knowledge and expertise. Sadly, I have to admit he's not the greatest writer in the world. The prose is kinda flat, especially given the material he has to work with.
At the same time, I'm reading Kurt Eichenwald's Newsweek portrait of the businessman (?) Trump, which probably contains some of the same information, but Eichenwald's style is far less dry.
