The concept of 'planned obsolescence' has been a subject of considerable debate among economists and environmentalists. Originally coined in the 1950s, it refers to the deliberate design of products with a limited useful life, encouraging consumers to purchase replacements more frequently. Proponents argue that this strategy stimulates economic growth by driving demand and fostering innovation, as companies continuously develop new models with enhanced features. However, critics contend that planned obsolescence exacerbates environmental degradation by increasing waste and resource consumption. They advocate for a shift toward a circular economy, where products are designed for durability, repairability, and recyclability. Recent studies suggest that while such a transition may reduce short-term profits for manufacturers, it could yield long-term economic and ecological benefits by lowering production costs and preserving natural resources. The challenge lies in balancing consumer expectations for innovation with the imperative of sustainability.
