I recall a millionaire couple (older folks, maybe 55-60) I knew when I was a kid - they built and operated nursing homes; I recall very clearly them with an architect's ruler going over the blueprints for a new building. They worked on a farm, and were themselves the son and daughter of farmers going back many generations. Education level? 8th grade education.
