Forbes has its latest figures for the world's richest people, and our very own Mayor Bloomberg is number 13, with an estimated net worth of $27 billion. Forbes writes, "Mayor Mike is $5 billion richer than he was this time last year thanks to the performance of Bloomberg LP, the financial data firm he founded in 1982 after being fired from Salomon Brothers."

Also, Forbes notes, "Bloomberg has a new mission for his post-political life: eradicating gun violence. He's emerged as a leading donor to pro-gun control causes and candidates. Many see the February victory of anti-gun candidate Robin Kelly in an Illinois congressional primary as a tipping point: Bloomberg spent some $2 million backing her through his Independence USA super PAC." It's shocking Forbes didn't include the fact that Bloomberg loves the free Staten Island Ferry for dates.

Of course, another notable billionaire/political force is David Koch, whose net worth is $34 billion, making him the richest New Yorker. He was "bitterly disappointed" that President Obama won re-election. Bloomberg endorsed Obama for re-election, but what he and Koch have in common is hating higher taxes.
