In daily life, people always buy the stuff they need and the stuff they want to have. The difference between wants and need is the living condition that the consumer was in currently. When you need something, you need it because it is a requirement for you in your daily life. For example, wholesome foods, and new clothes every 2 or 3 months. In opposite, when you want something, you don't really need it. It's just an accessory that you would willing to buy. For example, you don't really need to get the newest technology that just came out on the market. In fact, people always wanted the newest product or try out the trends that are thriving today. I think that people in the modern era buys what they want more than what they need. You would rather need something to survive more than something that you have for excess.
