Note: My criteria in determining the winners from the losers is quite simple; 1) Did you made a lot of money in your chosen "profession" ? 2) Did you better your life, and that of your family, by setting them up with generational wealth, gave them an education, and elevated future generations for a better life? 3) Were you able to avoid serving prison time, or, in the alternative, served very little time behind bars? 4) Were you able to enjoy your wealth and did you die in your own bed with your shoes off?
