Actually the people who discuss risk IN REAL LIFE do cover those things. In this /. discussion, not so much.
Risk is just one face of a many-faceted issue.
Other faces include responsibility, liability, and morality.
The liability facet is usually discussed by lawyers and financial groups. How much of the problems do we need to pay for? If we pay up front can we avoid paying later? These groups will often talk about reducing risks in an effort to cut bottom-line costs.
The responsibility and morality facets are usually discussed by social and humanitarian groups. Are we able to do something about it, and ought we do something about it? These groups will often talk about reducing risks in an effort to improve the lives of people.
