I'm not sure why you insist on giving your entirely wrong calculation, when I have already shown you a
correct one. In the above, you are doing a lot of double counting of money the government is already spending (directly on healthcare, by the way, which is where, unlike almost every other area of the economy, we have too much demand relative to supply).
Also, we strong negative feedback built into the economy. Extra money added to the system by the federal governent either is saved, in which case, there is no increase in aggregate demand, or it contributes to extra economic activity which generates taxable income which then takes money out of the system again in the form of higher tax revenues. The tax regime we have, by accident probably, is steeply progressive and generates revenues that rise superlinearly with both economic activity and inflation.
