"In the pharmaceutical sector, at first I thought researchers and doctors were admirable; then there were the executives, who sometimes did bad things. The worst, I thought, were the sales reps: they drank and even slept with doctors to get them to do the wrong thing. In the end, I completely reversed that moral hierarchy.

Almost all industry whistleblowers were sales reps. They earn less and have the least education, but the greatest moral fibre."
