> All arguments against salary transparency seem to be that people will be unhappy when they find out that the company has screwed them over and therefore it's better for these people to be ignorant.
Why do you assume someone making less is being "screwed over"? Imagine employees A and B. B greatly outperforms A and therefore rightly makes more. However, A is delusional about his skills and thinks he is as good as B. Pay information is made transparent and A sees he is making less. This makes him mad because by all rights he ought to be making as much as B! This type of comparison/resentment might make A want to quit or ask for a raise, whereas before he was both content and fairly paid at his performance level.
