The word "fair" in any context has NO OBJECTIVE MEANING. "Mutually acceptable" is the proper way to structure transactions. The usage of the word "fair" is meant to disarm an opponent ... manipulation by guilt (the unsuspecting will typically shy away from being accused of unfairness). Incidentally, "political correctness" is also manipulation by guilt ... exactly the same reasoning.
We on the right must NEVER fall into the "fairness" trap. And we should call the Left any time they pull that cr@p.
