GAO questions sustainability of USPS "The Government Accountability Office has questioned whether the United States Postal Service should continue to be self-sustaining. In an April 29 report to Congress, the GAO cited the Postal Service’s massive deficits and suggested it will need more taxpayer dollars to continue its “critical role in the nation’s communications and commerce.” The report noted that USPS losses now total $87 billion, including another $8.1 billion in 2020."
