From the Recalculation perspective, the economy needs to shift resources out of some sectors and into others. The government is either (a) permanently shifting resources from the private sector to government or (b) temporarily shifting resources from the private sector to government. If it is doing (a), then we are not facing mere temporary deficits but permanent increases in government spending, and eventually we will have to figure out how to pay for them. If it is doing (b), then the Recalculation problem isn’t really being solved. Instead, at best the government is redistributing the pain from the reallocation process out of the present and into the future. People who otherwise would be unemployed can find temporary work on government projects, but when those projects expire they will go back to being unemployed. This is what makes the fiscal exit strategy so problematic.
