A recent article on CNNMoney.com discusses the four major government expenditures that are eating up US tax dollars: Social Security, Medicare, Medicaid and interest on national debt. According to this article, the government currently spends $0.76 of every federal tax dollar on these four expenditures. What is even more alarming are the projections made by a simulation done by the Government Accountability Office, which estimate that by 2020, $0.92 of every federal tax dollar will go to these four expenditures. This will present serious limitations on what the government will be able to do in the future, as it leaves only $0.08 of every federal tax dollar for all other expenditures.
