Please tell me what private industry employs judges.
Is that really your argument?
No offense, but this is just a stupid line of reasoning. Private industry employs people with the same skills as those held by judges. The government is competing with private industry to hire people with those skills.
With your reasoning, the competetive wage for any type of employment that does not exist in the private sector is zero. Judges should be paid nothing, our military should be paid nothing, so on and so forth. Anything more than zero and these public sector employees are nothing but greedy bastards.
