In fact, the only alphabet agencies that the government should run are the CIA, FBI and the USPS (since it's mandated by the Constitution). America's prosperity will return when the Washington, DC unemployment rate is north of 80%.
You forgot the millions spent each year on the VOA including the Arab TV network nobody watches. Unfortunately, some conservatives (who like foreign propganda) have a blindspot on this.
BTW, the USPS is not “mandated” by the Constitution which merely says that the Congress should have the power, should it wish to exercise it, to build and maintain post roads.
