Even with fiscal room to maneuver, observation shows that is unlikely government can bring itself to pull the correct levels in the short term swings of business cycles, furthermore the fiscal economic guidance of what to do is unclear. The only clear economic lever pulling successes of the last several decades have been in monetary policy, and even there we have had mistakes (easy Greenspan money 01-03).
These are sort of competing problems here. The major problem with fiscal policy is that it's lagging because of how slowly spending measures move through Congress. So even though monetary policy has less of the desired effect, we use it more because it's more administratively efficient.
But I'm not talking about making wild rate swings left and right all the time. Just that fiscal policy is only effective when it's actually used and different situations call for different rates. Sometimes you need to raise them and sometimes you need to cut them. They can't be set in stone. As for the effect on business operations, I think that's pretty easily avoided by not taxing business operations.
How about 25%? Keynes himself apparently said, "25 percent taxation is about the limit of what is easily borne."
As far as I know, empirical studies have indicated that 40% is the marginal rate at which the taxed activity starts to be significantly discouraged. You see this with nurses. When overtime starts knocking them into the highest bracket, they stop working overtime.
But what the number is doesn't matter. The point is just that there is a point at which tax rates get too high and we should cap them and allow flexibility beneath that cap.
Consider that the savings (instead of investment/spending) in that bracket may well be due to http://en.wikipedia.org/wiki/Permanent_income_hypothesis" of the pending rate increases. Take away that threat, and I suspect investment and spending will start to climb again, in a matter much more likely to increase employment than when the government takes tax money out for stimulus joy ride.
High-income households have high savings rates regardless of future tax forecasts. Shifting wealth from low- to high-MPC consumers will always have a short-term stimulative effect. That isn't to say it's always the right thing to do, and that's why I qualified the "theoretical projection of effect" above with caveats regarding negative long-term effects. Plus, at a certain point, it's unethical to just confiscate money. Still, there will always be a short-term stimulative effect when you take money that isn't being spent and spend it.
The US has been unable to run up debt in this downturn?
That isn't really what I meant. The government, practically speaking, can issue damn near as much debt as it wants to. But when you run up debt during boom times, you cripple your ability to act prudently during busts. Because now, passing a debt-funded spending package doesn't simply create debt, it creates excessive debt. The proper way to do it is to run surpluses during boom times and deficits during busts to maintain predictable service levels in the face of volatile national income and to smooth the business cycle. Running a deficit all the time just results in a permanently increasing national debt that kills the future. If you run a deficit during booms and then cut back during busts, you just worsen the business cycle and turn booms into bubbles and busts into depressions.
