Human wants seem endless. When a starving man gets a meal, he begins to think about an

overcoat; when an executive gets a new sports car, visions of country clubs and pleasure boats dance into view.

2. The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears.

3. The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears: clothing and some tort of shelter. By the end of World War U these wants were satisfied for a great majority of American. Then a third level appeared. It in eluded such items as automobiles and new houses.

4. By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the "life enriching" level. While the other levels involve physical satisfaction——the feeding, comfort, safety, and transportation of the human body——this level stresses mental needs for recognition, achivement and happiness.

5. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental care, and entertainment. Also included fancy foods and the latest styles in clothing. On the fourth level, a greater percentage of consumers&39; spending goes to services, which on the first three levels more is spent on goods.

6. A fifth level probably would involve wants that can be achieved best by comunity action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety and leisure to enjoy more fully the good things on the first four levels.
