New York Mayor Mike Bloomberg is no longer the wealthiest New Yorker according to Forbes Magazine. Tea party backer David Koch is now number one after his income soared from $16 billion to $21.5 billion in 2009. The New Yorker magazine recently revealed that David Koch and his brother Charles have quietly helped bankroll the tea party movement and dozens of other right-wing causes. The New Yorker’s Jane Mayer reported the Kochs are longtime libertarians who believe in drastically lower personal and corporate taxes, minimal social services for the needy, and much less oversight of industry — especially environmental regulation.
