Hmm, what a controversial question? Some people will argue with you that it is not possible to get rich without being unfair or playing unfair. 

Well to me it is possible to play fair and be rich. Everything boils down to our belief and mentality. If you are the one with the mentality that one need to play unfair before he or she can be rich then being rich without being unfair will be difficult for you to do because of your belief that one need to play unfair even if the opportunity to do otherwise is presented before you, you will still one to play unfair.

Let know one deceive you, you can be rich without being unfair. All you need is your belief in yourself and God given talent and brain, the mentality of i can be rich without being unfair, patience and the ability to persevere.
