For years, my scientist brother Tom was the nonpolitical Stossel, writes John Stossel. I defended free markets on TV, and he studied blood at Harvard and Brigham and Women's Hospital. Mom asked me when I'd get a "real job" like his. Then the crusade against capitalism reached his world. Medical "journalists" demanded that corporations distance themselves from medical research. They'll bias the results, "put profits before people," and sell dangerous goods. Tom didn't notice this "conflict of interest crusade" until he joined the scientific advisory board of a biotech company and learned how difficult it is to bring medical innovation to market. Now, writes John Stossel, he's furious about what he calls "pharma-phobia."
