Todays Luxuries Are TomorrowsNecessities

　　By luxury, we mean a pleasant and often expensivething that is not necessary. From a historical point of view, thingswhich Were a luxury when they first came into being all became necessitieslater. When the electric bulb was first invented in the U.S., it was such aluxury that only government bodies could afford to use it. Nowadays, however,it has reached every part of the world. It is the same case with telephone, TV,and a lot of others, which were all luxuries years ago.

　　Anything, no matter how luxurious it is, will become a necessitywhen it is widely used. This is true of many of the present luxuries, includingmobile phones, cars, computers and many other things. It is known to all thatthe purpose of the development of science is to make things easy for themankind, not for only a small number of people. Therefore, the first thing todo after a new invention occurs is to spread it so as to benefit as many peopleas possible. In the course of the spread, the luxury becomes decreasingly luxuriousuntil in the end it becomes a necessity. This is an objective law, nothing canbe an exception.

　　With the quick development of science and technology, the processfor many things to become a necessity from a luxury will be greatly shortened.Anything that can be imagined will be invented and in no time becomes anecessity accessible to ordinary people.
