Planned obsolescence is a strategy used by manufacturers to design products with a limited lifespan, encouraging consumers to replace them more frequently. This approach can lead to increased sales but often results in waste and dissatisfaction among consumers who feel pressured to buy new products. The concept can be seen in various industries, from electronics to fashion, where items are intentionally made less durable or updated regularly. This practice raises ethical questions about sustainability and consumer rights, as it prioritizes profit over environmental responsibility and long-term value for customers.
