There are several reasons why people may not be as happy as they were decades ago. Here are a few possible explanations: 1. Increasing materialism: In today's consumer-driven society, there is often a focus on acquiring material possessions and financial success. This constant pursuit of wealth and possessions can lead to a lack of fulfillment and genuine happiness. 2. Social comparison: With the rise of social media, people are constantly exposed to the seemingly perfect lives of others. This can create feelings of inadequacy, envy, and dissatisfaction with one's own life.
