American Public Radio's This American Life is reporting a story that undermines the claims of success for the Clinton-era reform of welfare.  After the legislation was passed by Congress welfare rolls dropped by half in two years.  Where did all the people go who were dropped?  The assumption at the time was that they found jobs.  But NPR reports strong evidence that millions simply moved from welfare to the Social Security disability program.  Growth in the program exploded in a few short years.  States hired companies to push people from welfare onto the rolls of the disabled to save money.  Welfare is jointly paid for by both the states and the federal government.  Social Security is paid for entirely by the federal government.
