Stockman has a financial opinion which may be right or wrong. He has a shady financial past which may be true or not. But since no one is buying the book or reading the book or wants to spend $20 dollars on the book, then I have nothing to say.
We don't know all the truths, and just about EVERYONE that goes to Washington either is shady up front or comes out with some shade, more than others. I could name a bunch. Hope your day is going nicely Bess.
I remember David Stockman well. He was Reagan's budget director and implemented "trickle-down" economics (tax cuts), now referred to as supply-side economics, because it sounds better. He later decided it didn't work because of the large deficits it produced. Not many people ever admit they were wrong. That's why I remember him.
