The U.S. government has 15 different agencies overseeing food-safety laws, more than 20 separate programs to help the homeless and 80 programs for economic development. These are a few of the findings in a massive study of overlapping and duplicative programs that cost taxpayers billions of dollars each year, according to the Government Accountability Office. A report from the nonpartisan GAO ... compiles a list of redundant and potentially ineffective federal programs. The GAO examined numerous federal agencies, including the departments of defense, agriculture and housing and urban development, and pointed to instances where different arms of the government should be coordinating or consolidating efforts to save taxpayers' money. The agency found 82 federal programs to improve teacher quality; 80 to help disadvantaged people with transportation; 47 for job training and employment; and 56 to help people understand finances. Reducing or eliminating duplication, overlap, or fragmentation could potentially save billions of tax dollars annually and help agencies provide more efficient and effective services," the report said.
