That is actually a reflection of the whole problem with this legislation. It is not aimed at eliminating wage discrimination. Indeed, if you read the entire text from cover to cover, you will see that nowhere does it mention wage discrimination and nowhere is there any comparison between female and male jobs. What is discrimination, really? Any form of discrimination is always based on a comparison between two groups. But this Act, in terms of its structure and the language it uses, does not even refer to that problem.
