Lack of price transparency hurts the person with less negotiating power in a transaction. Most people are not VIPs who can demand compensation, so the employer benefits by knowing more about the market since they are constantly hiring vs someone who only looks for employment once a year, if not once every few years.
Additionally, lack of price transparency hurts the market as a whole, since prices are how the market conveys information as to where supply is needed. Restricting this supply is good for those benefiting from the extra profit, but not for society overall.
or maybe the spirit of a free and open society, where everyone is subject to objective evaluation and performance of his/her own work instead of opaque decisions in HR?
