In his 1930 essay "Economic Possibilities for Our Grandchildren ", John Keynes, a famous economist, wrote that human needs fall into two classes: absolute needs ,which are independent of what other have ,
and relative needs ,which make us feel superior to our fellows. He thought that although relative needs may indeed be insatiable (无止境的) ,this is not true of absolute needs.
Keynes was surely correct that only a small part of total spending is decided by the desire for
superiority .He was greatly mistaken ,however ,in seeing this desire as the only source of insatiable
demands
Decisions to spend are also driven by ideas of quality which can influence the demand for almost all
goods, including even basic goods like food. When a couple goes out for an anniversary dinner, for
example ,the thought of feeling superior to others probably never comes to them. Their goal is to share a
special meal that stands out from other meals.
There are no obvious limits to the escalation of demands for quality. For example ,Porsche, a famous
car producer, has a model which was considered perhaps the best sport car on the market. Priced at
over $120,000,it handles perfectly well and has great speed acceleration. But in 2004 the producer
introduced some changes which made the model slightly better in handling and acceleration. People who
really care about cars find these small improvements exciting. To get them, however, they must pay almost four times the price.
By placing the desire to be superior to other at the heart of his description of insatiable demands,
Keynes actually reduced such demands. However, the desire for higher quality has no natural limits.
