I'm under the impression that we are operating with the situation the US had as of the day Nym90 became President. That means that the budget is exactly what it is IRL except with a few billion in new spending here and there.
If that be the case, I do have a plan:
1. Roll back Bush tax cuts on incomes over $100K
2. Excempt S-Corp income from tax cut rollbacks (might require overhaul of tax code and redef of S-Corp).
3. Raise SS retirment age to 70.
This should be adequate to balance if we don't raise defense spending. If we lower defense spending, we can make more of the Bush cuts permanent (to appease the AFRNC), and raise spending on education (to appease the Left).
Personally, I would like to see a substantial increase in education. It's such a tiny percentage of the budget, we can afford to increase it by, say, 50%, without much impact on the whole budget. This would reap enormous political capital.
Change the repeal of the tax cuts to 250K at least. 100K is middle class.
The phrase middle class is the most vague term in American politics.
