Try your hand at balancing the federal budget

US Federal Budget sim created at Berkeley.
This simulation asks you to adjust spending and tax expenditures in the the 2004 budget proposed by the White House in order to achieve either a balanced budget or any other target deficit...According to the White House, the 2004 fiscal deficit is projected to be $307 billion. This does not include the costs of the Iraq War, so it has been increased by a base estimate of $50 billion for those costs in this simulation (which can be increased, lowered or eliminated depending on peoples views of the costs or likelihood of the war.).
