Why change if it works?

I don't necessarily feel using the term "Professional" is the correct way to describe what is being discussed here. I feel the better way to describe what holly wood is doing is to see the big picture... If something works, why would you change? If a reality TV actor/character does well and brings in the "BIG BUCKS", I don't see a big "WHY NOT?" in trying to keep the viewers/their money, by adding little twists to the show or character. If they already have a viewing fan of x amount of people, why not utilize what you already have instead of taking a step backwards and setting up a whole new show with new characters. Also, there is not necessarily a "IS THIS FAIR" question to ask because in reality, who cares. Even if you are an actor, I don't think you would be trying to get a job as a REALITY TV artist. If you get the job, awesome, if not, don't be disheartened, there is something better waiting for you. :)
