In the nineteenth century there were some people known as professional gamblers. Typically, these people did not work for a living (in the usual sense of the word, "work"). Probably because of this, they were looked down upon by most of society (that, plus the fact that they were predators). Could the stock trader be the twenty-first-century equivalent of this? (After all, he does not contribute anything to society--either a product or a service--but merely takes from it.) Thoughts?
