I will put forth the argument that profit is not be the sole motive for any organization. That is a relatively new and immature [1] way of thinking about economic activity which ignores the context and environment in which economic activity takes place. Profit above all else should be considered the false narrative that it is [2]. Even if we did consider profit to be a primary motivation for an organization, that ignores that the organization is composed of people who should care about their fellow man and work to reduce the chances and effects of injuries in the people who labor for them. I will go further and propose that putting profit above the long term health of players is short-termism, a disease that affects far too many today. In fact, this disease of thinking is so bad that the executives of some of the largest corporations now need to explicitly tell people to stop thinking like that [3]. Ignoring the dangers of traumatic brain injury could have negative consequences for the long-term profit of the NFL - through lawsuits, negative publicity, and less productivity from the players.
