I'm really tired of being the only person who takes even cursory glance at the actual spending numbers.
For 2011 (estimates):
43% of expenses are paid for with loans. We would need to cut spending by 43% to break even.
Defense: 25.2% (ALL military activity. Cutting would be extremely difficult and most likely entirely blocked by republicans)
Health Care: 23% (Political suicide to cut)
Pensions: 20% (MAY NOT be decreased, contractually required)
Welfare: 12.9% (Political suicide to cut)
Interest: 5.4% (Interest on debt. MAY NOT be cut, this represents the increase in debts due to interest. Cutting this would be defaulting)
Education: 3.3% (129b $)
"Protection": 1.5% (Fire, Police, and the justice system)
General Government: 0.86%
Other: 4.1% (including:)
Housing Development: 0.92%
Agriculture, Fishing, Forestry, Hunting, departments 0.85%
Basic Research: 0.48%!!! (All basic research...)
...Many, many other items in the <0.1%-0.8% range...
NASA accounts for 0.58% of total spending.
Everything that I have not mentioned accounts for spending so small and insignificant that they can be completely ignored in any rational debate. (Federal Payroll (outside of pensions), office decorations, art subsidies...)
Cut 43% from that without crippling the United states while still making a plan that both sides will agree on. And when you're done, spin this straw into gold and beat Chuck Norris in a beardfight.
The fact of the matter is, the only fiscally responsible thing to do is to pay more taxes. My advice is to delete defense spending. Take it down to 10%. Destroy healthcare and rebuild it responsibly, in a way that respects doctors and patients instead of HMOs, and cut spending on it significantly. Let's say a total decrease of 5%. Pension reform has been a long time coming. I really don't know if it's possible to decrease our current expenses there, but we need to renegotiate these contracts. Scott walker should drown in a bog of pig offal, no question, but real negotiations need to take place.
Increase spending on Education, NASA, Basic Research, and federal grants to nonprofit associations by a total of 3% of current spending and basically double visible public spending.
Making Pot legal would not have a significant effect on the 1.5% of the budget spent on civil protection. Taxing it might. Same goes for the TSA. Not a significant spending.
That's total cuts of 30%. Close corporate loopholes*, keep taxes the same for everyone netting less than $1,000,000 a year, Legalize and tax pot, if not vices in general, (the Dwarf's Penny tax), and finally, increase taxes on the +$1,000,000** (if needed) for the remainder.
I'd remind everyone that of all those expenses, the DoD probably puts the least back into the economy... even wages probably get spent elsewhere.
*Admittedly vague, but for a start, I'd require companies that do business here to pay US taxes on sales here even if incorporated elsewhere, on pain of death.
** Currently trust fund managers accrue huge tax-free incomes since they don't "earn money" they just "own things that appreciate in value". This is a irrelevant distinction both in practice and in accounting theory. Also, it is common enough for someone to make a large amount of money on paper and then lose it again within a year, leaving them unable to pay taxes on the income. While leniency here could lead to abuse, it may be reasonable to tax everyone based on how much their net worth increases in a year rather than how much money they receive; this is how corporate taxes would work (if corporations paid taxes).
