While I support all efforts at increasing information transparency, I disagree that prices need to be the same. It is possible that humans are sufficiently different in the quality of the labor they are selling that a buyer might price them differently.
For example, I am willing to pay a higher price for someone has 10 years of experience and is less likely to make mistakes or other desirable qualifies more than someone who has 0 years of experience, even though they are doing the same work.
