Forty, count 'em, forty millionaires have volunteered their fellow millionaires to Obama for increased taxes.  Given that there are 7.8 million millionaires in the US, these 40 represent five ten-thousandths of one percent of the millionaires in the US (or 0.0005%). 

So what's stopping them from giving more money in taxes than they currently give to the IRS?  Nothing....except that they are Leftists.  So they don't want to give their money to the government, they want to give other people's money to the government.  That's how Leftists work, even millionaire Leftists.
