Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat, when
a manager gets a new sports car, a big house and pleasure boats dance into view.
The many needs of mankind might be regarded as making up several levels. When there is money enough
to satisfy one level of needs, another level appears.
The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs,
clothing and some sort of shelter, appears. By the end of World War Ⅱ, these needs were satisfied for a great
majority of Americans. Then a third level appeared. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of
needs appeared; the "life-enriching" level. While the other levels involve physical satisfaction, that is, the need
in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and
happiness. 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 recreation. Also included here are fancy goods
and the latest styles in clothing.
On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on good
s. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to
demand luxuries and personal services on the fourth level?
A fifth level would probably involve needs that can be achieved best by community 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.
