'No, really, ignoring the drop in tax revenue is gonna work fiiiine.
In 1969; the median average household (we can call that the middle class for convience) made $37,559 and was taxed at 45%. At the same time, the highest median tax rate was 77%. Government revenue of 18.98% of the GDP.
In 1999 the median average household (again middle class) made $50,046; and was taxed at 28%. At the same time, the highest median tax rate was 39.6% Government revenue was 19.54% of the GDP.
You can see how the government in 1969; with a tax rate 1.6 times that of 1999 on the middle class, and 1.94 times that on the richest, brought in 0.56% LESS revenue as a percentage of GDP.
In fact, if you don't believe me; look at
THIS graph. You can see how US Government revenues fall in the nice 15% to 20% band overall.
Then compare that earlier graph with
THIS one.
But lets humor you. Lets say that we double tax rates across the board and raise the percentage of GDP collected as taxes to 20.79% of GDP which is the biggest we ever got it to, in 1976.
You would only raise $3,033.261 billion; and outlays are $3,518 billion for FY09; still leaving you a nice $484 billion in the hole.
The biggest slices of the Federal budget outlays are as of 2009:
Defense: 782B (23%)
Social Security: 678B (20%)
Medicare/Medicaid: 676B (19%)
Other Mandatory: 607B (17%)
Other Discretionary: 437B (12%)
Interest on Debt: 187B (5%)
TARP: 151B (4%)
You would have to cut the Military budget by 61%; in order to even BRING us close to a balanced budget.
This tactic would only push off the reckoning by 25 years, due to the looming Medicare/Social Security bomb. Right now, both are in the red, paying out more than they take in.
Now; normally....this would not be a problem; since both programs (SS/Medicaid) have trust funds intended to cover precisely this kind of stuff.
But there's just one catch.
There ARE no assets left. The trust funds got raided years ago to fund government operations.
So money has to be taken from the general government fund in order to meet Social Security costs (otherwise people see their checks stop or cut in amounts).
How bad will it get?

You can see the projections leading to nice deficits of $300B by 2020; and then $700B~ by 2035 (Holy christ batman!!!).
So spending cuts are inevitable, unless you want the government to simply become "those guys who pay out entitlement program checks" with nothing left over for national parks, industrial regulation, etc.
Now; you can take your strawman about military spending and shove it up your ass.
I am not opposed to military budget cuts -- we can do with a smaller Army and Marine Corps, and some decrease in the size of the USAF and USN; as long as we reduce forces intelligently (e.g. get rid of fighter wings with 200 F-16s in them and use half of the money saved to pay for more F-22s or F-35s for the remaining fighter wings to increase lethality).
But why is it that the military is always the first (and in many cases only) case that idiots like you look when the U.S. Federal budget needs to be cut?
If the MIC is bloated, then so is the Government Agency/Regulatory complex.
For fuck's sake, the Federal Register in for the last ten years has averaged about 70,000 pages a year.
Companies have to basically hire services who do nothing but read the FR every day to find things that would impact that sector's operations.
Cut down on the god damn regulation spam and hire more enforcement personnel to inspect and audit company sites instead of writing regulations.
