Question: Adam was a university graduate with a double major in economics and art. A few years ago, Adam decided that he wanted to pursue a vocation that utilized both of his talents. In response, he shut himself up in his studio and created a watercolour collection, "Graphs of Famous Recessions." With high hopes, Adam put his collection on display for buyers. After several years of displaying his econ art, however, the only one interested in the collection was his eight-year-old sister, who wanted the picture frames for her room. Recognizing that Adam was having trouble pursuing his chosen occupation, Adam's friend Karl told him that the market had failed. What do you think? Is Karl right?
