"Billions of dollars deducted from paychecks issued to undocumented
workers flow to the Social Security Administration (SSA) every year.
Those workers almost certainly will never see that money again. Social Security officials keep a record of wages that do not match up
with real names and numbers in their system. The record is called the
earnings suspense file. In 2009, the last year for which figures are available, employers
reported wages of $72.8 billion for 7.7 million workers who could not be
matched to legal Social Security numbers. That total hit a record $90.4 billion, earned by 10.8 million workers, in 2007, just before the recession." - Cox News, Dec. 28, 2011.
