Last week, Forbes annointed Michael Bloomberg the richest person in New York with a net worth of $20 billion. The Wall Street Journal offers up a handful of reasons today why he's probably not worth that much, at least after the events of last week: "If Bloomberg were publicly traded, its stock likely would have taken a dive this week... There are now two fewer investments banks buying Bloomberg terminals, not to mention the thousands of finance workers who also will lose their jobs—and their terminals—this year." [WSJ/Wealth Report]
