Tech’s biggest loser: Bill Gates

The collective net worth of the super rich on Forbes's annual list of the 400 wealthiest Americans fell by $300 billion over the past 12 months, and the tech sector spilled its share of the red ink.

Microsoft's Bill Gates lost the most -- at least on paper. His net worth dropped from $57 to $50 billion, not enough, however, to keep him from topping the list for the 16th year in a row. Two current and former Microsofties were close behind: Paul Allen (No. 17) lost $4.5 billion and Steve Ballmer (No. 14) gave up $1.7 billion.

Other notable losers were Michael Dell (No. 13), down $2.8 billion, and SAS's James Goodnight (No. 33), off $1.9 billion.

In this company, the $600 million that Apple CEO Steve Jobs lost on paper doesn't seem so bad. In fact, on the strength of the $5.1 billion he still has, he moved 18 spots up the Forbes 400 list, from No. 61 to No. 43.
