i don't follow this argument.

thr salient point for me is that people should be able to see prices before they commit to contracting to pay them (e.g. by receiving healthcare).

With wages, employees (and employers) get to see their price before committing. So the need for transparency seems like it would need a different justification.

Price transparency is necessary for market participants to observe the movements of the supply and demand curves.

For example, declining prices of labor indicate to suppliers of labor to reallocate labor supply to other fields.

Increasing prices of labor indicate to suppliers of labor to reallocate labor supply to that field.

thanks for this explanation. it's something I've not thought about before and it's enlightening.
