In modern society, more and more unnecessary products are being created, and people’s consumption habits have changed accordingly. Many people buy things they do not really need, and some even replace old products with new ones for no good reason. The main causes are advertising and social pressure. Companies constantly use promotions such as “limited-time offers” to make us feel that we must buy right away, and social media makes us compare ourselves with others and want the latest products. I think that excessive purchasing of unnecessary products is not a good thing, but some special situations can be exceptions.
