That's not what managerial praxis means, it isn't when you manage people's health. Your manager does not care about your health at work. A parent who cares about one's health is now a manager too from this line, or a daycare worker. It's about the role in wage labor, not whether they vaguely have some professional authority in interacting with you in one aspect of your life. Opiate epidemic doesn't change that, especially when the vast majority of bribes went out to physicians.
