CBS Sunday Morning had a story on the 5/13/12 episode about Ruben Carter, an employee of a gas station in Joplin, who saved the lives of 24 others with his quick thinking during the EF-5 tornado that killed about 160 people. This was one case where having a person being "underemployed" proved to be a life saver for those around him at a critical time. Lee Cowan reports for CBS :
