but has a degree in psychology, spent 4 years and some good money and never used it.
A bachelor's degree in psychology is much like a bachelor's degree in "liberal arts." It's very much a generalist degree and is used by a lot of the colleges as a sort of catch-all for students who still don't know what they want to do if they ever grow up. To actually work in the field of psychology you pretty much need a graduate degree of some kind.
