First, three stories from Thomas Peterffy's life as a trader:
When Peterffy was a kid growing up in communist Hungary in the 1950s his buddy went to Austria and brought back a pack of Juicy Fruit gum. Peterffy bought the pack, broke the sticks of gum up into little pieces, and sold them at a profit. The principal at his school was not amused. "Where's your communist conscience?" the principal asked.
Not surprisingly, given story #1, Peterffy moved to the U.S. as a young man.
