While many — including the Securities and Exchange Commission — have questioned the role of credit-rating sevices in the current financial meltdown, you won’t be reading about it, as expected, in a forthcoming book from McGraw-Hill called Bailout Nation: How Easy Money Corrupted Wall Street and Shook the World Economy. That’s because — as Greg Bensinger details in this Bloomberg News report — author Barry Ritholtz, CEO of an equities research firm, withdrew the book because he said McGraw-Hill editors kept editing passages he’d written about one of the biggest credit rating agencies of them all, Standard & Poor’s — which, as it turns out in an amazing coincidence, owns McGraw-Hill. Says Ritholtz, “It’s kind of hard to write a book about the financial crisis without mentioning the ratings agencies.”
