Fraud In Social Security Disability : Unemployment Spill Over?

I wonder how this happens? It doesn't take rocket science to see how with the federal government bureaucracy being out of control by it size alone, could allow an agency like SSI becoming an easy mark for fraud. Add this to all the other agencies and departments in the government that are being defrauded on a daily basis, one can see where nothing will remain but chaos in our society.

A U.S. Government Accountability Office (GAO) report says the federal government may have paid $1.29 billion in Social Security disability benefits to 36,000 people who had too much income from work to qualify, says CNBC.

At least one recipient collected a potential overpayment of $90,000 without being caught by the Social Security Administration, according to the report, while others collected $57,000 and $74,000.
The GAO also says its estimate of "potentially improper" payments, which was based on comparing federal wage data to Disability Insurance rolls between 2010 and 2013, "likely understated" the scope of the problem, but that an exact number could not be determined without case by case investigations.

• To qualify for disability, recipients must show that they have a physical or mental impairment that prevents gainful employment, and is either terminal or expected to last more than a year.
• Once approved, the average monthly payment to a recipient is just under $1,000.
• In fiscal 2011, more than 10 million Americans received disability benefits totaling more than $128 billion.
