Wants - Simply the desires of citizens. Wants are different from needs as we will see below. Wants are a means of expressing a perceived need.
Wants are broader than needs.
These are basic requirements for survival like food and water and shelter. In recent years we have seen a percieved shift of certain items from wants to needs. Telephone service, to many, is a need. I would argue, however, that they are wrong. Scarcity - the fundemental economic problem facing ALL societies.
