Affluence


      There is one thing that most people desire for all their lives, and that is affluence. They pursue wealth in their whole life, and feel confident because of having much money. So they try various ways to earn as much as possible. They think being rich is considerably enjoyable. A rich life is interesting, and is filled with variety, because money can help them to do different things.
      They can rush into department stores to purchase lots of expensive clothes and cosmetics without glancing at the prices. They can also afford the dear expenses of entertainment, so their life is wonderful and colorful. Luxurious furniture, high –quality household appliances and comfortable housing conditions provide a convenient and easy life for them. They don’t have to worry about economic problems any more. For them , enjoying the material abundance is much more important than possessing spiritual abundance. What’s more, wealth brings them a higher social position. They use a little amount of money to patronize the poor and win some respect and enjoy a good reputation.
      A rich life seems exciting and happy, however, every coin has tow sides. When they get much money, they are worried about the safety of money, and they are afraid of thieves and robbers who will steal their money. Therefore all of these that annoy them can often become their nightmares. Besides, sometimes the sharp contrast between material abundance and the spiritual poverty makes them feel dejected and depressed. So money does not always equal happiness. Despite some people are poor, they are living a pure happiness of the simple life. As for the rich people, the more money they have, the more they get worried. For example, they usually think about how to make more money and how to spend money, which bothers them terribly. Then they realize that wealth brings them so much trouble and to be rich is not as attractive as they have imagined.
