[originaltext] When I arrived in America three years ago, I was surprised by

When I arrived in America three years ago, I was surprised by the tremendous amount of advertising. But now I’ve come to realize that it is a creative and necessary part of an industrial society. I, too, want to improve my life style and to buy better products. I look to advertising to show me how to do it. Deciding what to believe in an advertisement, however, isn’t easy. It seems to me that a person must purchase things with a lot of care. As a consumer, I want to get the best for my money so I really have to understand the techniques of advertising. Otherwise, manufacturers would be able to sell me anything, whatever its quality may be. The creative aspects of advertisements, for instance, often cover up defects or problems in products. I have learned this well, since I have made purchases and lost money because the items were of poor quality. The future advertising most likely will involve more public participation. In the future, if customers really care about the quality of something as well as the quantity, maybe advertisers will begin to care more about what they are trying to sell.
