I have a close acquaintance who is an executive for a company that creates drugs and sells their creations to big Pharma. They focus on cancer treatment. He recently confessed to an ethical problem he has with their work. They focus on treatment that will extend the life and comfort of someone who has cancer. They do not focus on either prevention or a cure, and he said that is true throughout the industry. Give it some thought and you will see why. Once the polio vaccine was created, all the companies making billions of dollars treating it were out of business.They want the people addicted to what they are selling, good for their business, who cares about their health.
