Money just might be able to buy some people happiness -- depending on their social class. A new study found that people in different social classes experience varying levels of happiness from specific types of purchases. Researchers from several universities wanted to determine the best way to spend money in order to increase happiness. After conducting a series of studies, researchers found that wealthier people derive more pleasure from buying experiences or trips, like concerts or vacations. Meanwhile, people with less money reported more varied results, some said they derived the same level of happiness from both physical goods and experiences, while others felt happier with new toys as opposed to a vacation or event. The study was published in Psychological Science.
