The article discusses how companies use wage comparisons to decide on fair pay for their employees. They compare wages with other firms to make sure they are paying competitively. This is important for keeping workers happy and preventing them from leaving. However, it's getting harder to compare wages accurately because of the rise of fringe benefits like healthcare and retirement plans. These benefits make it tricky to measure and compare wages between companies. So, even though comparing wages is seen as fair, it's becoming more challenging to do so accurately due to the complexity of modern compensation packages.
