In this Crisis of Science podcast which he goes into at length, he often cites commercial interests as being the root cause of the corruption of science. He does refer to government agencies that collude with private interest, but stops short there. Corbett doesn't offer solutions, and says that "this isn't simply a problem of money" that is at the root of the crisis. He refers to the crisis as "having social-political and structural roots". (If he only knew!) He promises to examine various proposals to solve this crisis in the next podcast. I can't wait.
(If you are scientist or academic, I recommend this article entitled "The Commercialization of Science and the Struggle Against It" by "Denys Bondar, a young Ukrainian scientist working in one of the famous North American universities" [Princeton] from LeftEast, a website based in Bulgaria.)
