You say: “The argument for a higher inflation target is straightforward, once you understand two things. First, the most effective and reliable monetary policy instrument is to influence the real interest rate in the economy, which is the nominal interest rate less expected inflation. Second nominal short term interest rates have a floor near zero (the Zero Lower Bound, or ZLB).”
The argument for a higher inflation target is NOT straightforward, once you understand two things. First interest theory is axiomatically false.#1 Because of this monetary policy never had sound scientific foundations. Second the same holds for fiscal policy.#2
Let us assume for a moment that, for whatever reason, neither monetary nor fiscal policy is applicable. So, given the investment expenditures of the business sector and the expenditure ratio of the household sector, the only alternative left is to directly influence the macroeconomic price mechanism.#3
The argument AGAINST higher inflation is that it REDUCES employment. Given the overall situation, the ONLY sensible policy is to increase the average wage rate, such that the rate of change of the wage rate is greater than the rate of change of productivity because this increases employment. This is a SYSTEMIC necessity and has NOTHING to do with social policy. Employment is co-determined by the relationship between average wage rate, price, and productivity. This relationship should automatically produce full employment but does not.
Standard employment theory is false.#4 The proposal to get the economy going by increasing price inflation is the direct result of the complete lack of understanding of how the market economy works.

You say: “For every borrower there is a saver.”
In this generality this is trivially true, nonetheless, it is grossly misleading. To see this, let us take the pure production-consumption economy as the most elementary case as a starting point (no investment, no government, no foreign trade). Wage income is denoted as Yw, consumption expenditures as C.#1
The sector balances (Sm≡Yw−C, Qm≡C−Yw) always add up to zero, i.e. Qm≡−Sm, that is, the business sector makes a monetary profit Qm which is equal to the household sector’s dissaving (-Sm) or a loss −Qm which is equal to monetary saving Sm. So, if the household sector dissaves it uno actu happens that the household sector becomes the borrower vis a vis the banking sector (including the central bank) and the business sector becomes the lender to the banking sector. When we cut the banking sector short the business sector becomes the ultimate lender to the household sector.
From this immediately follows that saving and investment are NEVER equal, neither ex-ante nor ex-post, and ALL Keynesian and Post Keynesian and New Keynesian and IS-LM models are provably false.#2
The same relationship holds when private households are substituted by public households. Therefore, the period deficit of the public sector reappears one-to-one as the profit of the business sector. When we cut the banking sector short the business sector becomes the ultimate lender to the public sector.
Needless to say that the business sector prefers the public sector as the ultimate borrower. This explains the safe asset shortage if the monetary profits stem from private deficit spending.
The deficit spending of the private and public households together determines the overall profit of the business sector. This means that Keynesian deficit spending is the ultimate profit machine if the household sector’s budget is balanced. Increased private and public deficit spending, in turn, explains the falling labor share.#3
Whether public deficit spending helps employment depends on whether the average price increases or not. In any case, though, public deficit spending helps profit one-to-one. So, whoever wants the maximum employment effect from deficit spending has to see to it that the price increase is zero.#4
Now, you are in favor of expansive fiscal policy and propose to increase the inflation target. This is as counterproductive as can be. The combination of increased public deficit spending and a rising price increases profit and leaves employment unaffected.
From the standpoint of the one-percenters, your policy mix is perfect. From the standpoint of the ninety-nine percenters, it is another instance of expert madness. The correct policy in the given situation is to put traditional=failed monetary and fiscal policy aside and to increase the average wage rate at ZERO price inflation.
