Question:

Two employees are equally productive workers, but Employee Number 1 is a better negotiator than Employee Number 2. As a result, Employee Number 1 earns 7% more pay than his equally productive counterpart. Employee Number 1 is male and Employee Number 2 is female.
Should the government intervene to ensure that both workers earn the same wage?
