Any physician CME instructor or scientist with the remotest connection to a drug company has to 'disclose' their conflict to the audience or reader. That is our standard in healthcare.
However, the government is rife with corruption. Executives from Monsanto sit on the board of the USDA. Government officials hold positions on Wall Street and with major corporations who receive government funding. Examples abound of corruption. It is not even hidden anymore, but well-known and obvious. If we ever want to take our country back, we will have to start with the corruption.
