Smaller Government means less Military, Health Care, or Social Security
If you want smaller government, than you want less military, smaller pensions, or less government intervention in health care. The broad category of welfare is in fourth place, but removing all welfare three times over still wouldn’t close the federal deficit. Foreign aid is around 1% of the budget. Furthermore, tracking down and eliminating waste isn’t costless, so generally such programs are net losers for the budget.
It would not be easy to balance the budget without serious cuts. If Congress cut the military back to the per-capita size of Britain’s military and eliminated all health care laws, that would just about do it. Entirely eliminating Social Security, Medicare and all federal welfare programs would also do the job.
