Insecure people buy branded products

What is the difference between a branded product and a local non-branded product? The first and big difference is the price. People who buy these products, even most of them also dont know the difference between a local cheap product and a branded costly product. They buy just because they think that if any product is costly it must be good.
       I know a guy who always buy branded products. whether it be clothes, bags, goggles or any other thing. When i asked him the reason for buying only branded products he replid that it is made up of good raw materials that are not harmful to our health. Then i asked him that how can he say that the local brands  will harm his health. He had no answer. When i asked him to tell the difference in raw marerials that a branded and a local manufacrurer uses. He again had no answer.
    This showed that these people who uses branded products are not using them for the physical benefits that a product provides but they use it for the psychological benefit that the price of these products are providing them.
