It's also hard because some of those "lavish" expenses are a necessity if you are famous and make your money from things like looks. Very famous people may need security in various forms that ordinary people do not need (bullet proof limo, security guard, housing with security). Oprah has said if she wears the same outfit twice in two months on her show, people have a fit about it and many stars have to pay for personal trainers, expensive haircuts, etc just to keep their "job."
