Forbes released its new list of the World's Richest People and our mayor is the richest person in the Big Apple (heck, his net worth even rose this past year!). Michael R. Bloomberg, who is also known as Hizzoner, is at #17 on the list, with his self-made fortune estimated at $16 billion, thanks to "a transaction [that] put a solid valuation on Bloomberg LP: he borrowed to buy a 20% stake in his company from Merrill Lynch in July for $4.5 billion." Is this why he's advising against taxing the rich? Former richest man in NYC, David Koch, is now the 2nd richest (#20 on the list, with a net worth of $14 billion). Also interesting: One of the many billionaires tied for #701 on the Forbes list is a Mexican drug lord.
