I am not sure if it is really clinically correct but it may just be the term to embrace a combination of narcissism, depression, loneliness, and paranoia. It is plausible that as the affluent gain more money, and their daily lives change, they slowly alienate friends, family and co-workers. Those of us who aren't uber-rich may think a night on the town, expensive drinks and dinner, and a taxi ride home is splurging but for the wealthy their private plane ride to a chalet in the Alps is just another day. Not being able to share their experiences with those they care for, they look for new friends that enjoy the same lifestyle they do. Loneliness and depression ensue and to fill that void the wealthy turn to the newest, hottest, most expensive vehicles, clothes and jewelry.
So enjoy your life with the perks and trials we all experience -- our mortgage, our car payments, budgets and bills. It could be worse -- you could have WFS!
