NOBODY SAID IT is easy to crack the Forbes magazine list of the 400 wealthiest Americans. And once you crack it, just being a billionaire doesn't always hack it.
Eighty-two billionaires were dropped from the 2007 list. Oh, the shame. The cutoff fortune was $1.3 billion. George Steinbrenner was a few bucks from not making the list. The Yankees' said-to-be-ailing owner tied for No. 380 and last with a paltry $1.3 billion, just $100 million more than the current valuation of his ballclub.
