what is the other 29%? Sounds like the important stuff is covered by 71%, so lets cut the other 29% to 10%. a net saving of 19%, much more than the annual deficit.
Nearly a quarter of the other 29% is paying interest on the national debt. You have to pay that or the debt will grow even larger. Other things in that 29% include, international affairs/diplomacy, General Science, Space, Technology, Agriculture, Administration of Justice, General Government, Energy, Natural Resources, Environment, Housing, Transportation, Community and regional development, Education, Training, Employment, Social Services, income security.
