When I talk about the relentless push of Big Business, the Right, and the GOP toward our current crisis of inequality, injustice, minority rule, and an inability to solve problems, I usually start around 1970. Today’s guests go back to the early 20th century when the National Association of Manufacturers (NAM) opposed laws vs child labor. Deja vu? I talk with NAOMI ORESKES and ERIK CONWAY, authors of the best-selling MERCHANTS OF DOUBT: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming, about their new book, THE BIG MYTH.
