The king, not knowing all that much about music, fishes for an answer and blurts out, "There are too many notes." Mozart answers, "Your Majesty, there are exactly the right number of notes." This is instructive about what is happening today when people claim that the deficit is "too big" or the the debt to GDP ratio is growing too rapidly. It's just uninformed. There is always a "right-sized" deficit/surplus relative to the sectoral balances. In extreme situations, the fight size of the deficit may be very large indeed, as it was when the US was fighting WWII. Should we have been concerned then that the deficit was getting "too big"? Obviously not. Should we be concerned now, when the US is greatly underperforming at great cost in foregone opportunity and huge degradation of resources, especially human resources, when something could be done to correct this? Instead being concerned with bogeymen, or appealing to "the confidence fairy" (h/t Paul Krugman), MMT looks at the economy through the macro lens of sectoral balances and the accounting identities that pertain. For example, it is an indisputable accounting identity that the budget balance, domestic balance and external (trade) balance sum to zero. This means that they cannot all be in surplus or all in deficit simultaneously; there are inevitable offsets to maintain balance among the sectors. The relation among the sectors has economic consequences affecting real resources and real people. This is usually overlooked in the uninformed discussion that are now taking place
