I don't think scare people's salaries should be based on their job performance. I have two reasons. In the first place, It should be changed from their performance to age. As they get older, many people will have their family, so they need a lot. of money. If their salavies base on age, they can live in peace. In the Second place, some people don't have the skills. For example, people who have disability may not have enough skills. If their salaries be based on r their age, they can't get enough money. Last of all I think people's salaries had better be based on their age. It has a lot of benefit than being based on their job performance. Mary people can live in peace
