The capability approach is a way of thinking about how we value people, especially in terms of their quality of life. It means that people should be judged based on what they are able to do with the resources they have, rather than what they actually have. For example, two people might have the same amount of money, but one could be able to do more with it than the other. The capability approach would say that the person who is able to do more has a better quality of life. So it is about having the freedom and opportunity to choose what you do with the resources available to you. It emphasizes the potential of people and their capabilities, rather than just their actual resources.
