Query: Snake Oil

The world needs a good book calling to task all the charlatans out there getting rich by offering advice on everthing from sex to getting rid of problem dandruff. Unfortunately, Tom Tiede's "Self-Help Nation" is not up to the task. The book is merely a disjointed collection of screeds against everything and everyone ranging from Thomas Jefferson, to Christians to modern newspapers to that always popular target--baby boomers. The book should be entitled, "Tom Tiede's Pet Peeves: a Self-indulgent Monologue." The book's cover promises readers an antidote to the "snake oil peddlers who are sapping our nation's soul." Instead, Tiede simply offers his own brand of snake oil in a package that promises an antidote but contains only colored water.
