Now that the grandest wedding ever is over, leaving a void on social media, let's tackle the age-old question: can money buy happiness? While the Beatles sang "Money can't buy me love," scientists are still exploring the answer. Recent research by Wharton's Matt Killingsworth tracked 33,269 employed US adults, including the ultra-wealthy with net worths between $3 million and $7.9 million. He found that the super-rich were significantly happier than those earning over $500k a year. The reason? It's about having more control and freedom to live life as they desire.
