What does this "need" mean? The performer's need or receivers'(customers, patients, the public) need?
ex)Although I do not think it is because of the pay that people choose to become doctors rather than receptionists, there is one qualification to be made to the suggestion that payment should be based on need rather than ability. The prospect of earning more money sometimes leads people to make greater efforts to use the abilities they have, and these greater efforts can benefit patients, customers, students or the public as a whole. It might be therefore be worth trying to reward effort, which would mean paying people more if they worked near the upper limits of their abilities, whatever those abilities might be. This, however, is quite different from paying people for the level of ability they happen to have, which is something they cannot themselves control.
