The main part of the $447 billion jobs plan proposed by President Obama in a speech to Congress on Sept. 8, 2011, is to reduce social security taxes. At a cost of $240 billion in government revenues in 2012, the Obama jobs plan proposes cutting the 6.2% social secuirty tax -on worker income up to $106,800- down to 3.1%. The current tax cut which expires in December 2011 cut the tax down to 4.2%. Analysts estimate this could generate over 500,000 jobs in 2012.
