Human’s Wants
   71   When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, versions of country clubs and pleasure boats dance into view.
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.
The first and basic level of wants involves food.    72   By the end of World War -Ⅱ these wants 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 wants was fairly well satisfied.    73   Rather than other levels , 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 care , entertainment, and fancy foods and the latest styles in clothing.    74    Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
