Good post, as always!
Let me add that I like to say it this way.
The purpose of taxation is to create unemployment as defined: people looking for paid work.
Govt does this to provision itself.
It taxes in something no one has- the $A- which creates sellers of real goods and services (unemployment) presumably so the govt. can then hire them to provision itself.
So what’s the point of creating more unemployed than the govt wants to hire? Or, said another way, what’s the point of creating the unemployed govt wants to hire and then not hiring them?
There is no point, of course, and wouldn’t be under by anyone who understood how it works.
Furthermore, the $A is a simple ‘tax credit’ as its only ultimate use is to pay taxes.
That is, when the govt spend a $A, that dollar is either
1. used to pay taxes and is lost to the economy, or
2. is not immediately used to pay taxes and remains outstanding until it is used.
The govt. allows those unused tax credits to be held in three forms- as actual cash, as cash balances at the reserve bank, or as balances in securities accounts at the reserve bank called Treasury securities.
The total of the three is the national debt.
The national debt is simply the total tax credits spent but not yet used to pay taxes.
And so the question of ‘how is it going to be paid back’ is entirely inapplicable!
So why does the economy need a deficit (tax credits spent and not yet used to pay taxes)?
Exactly as Bill says- to accommodate the desire to net save.
bottom line- unemployment is always and necessarily the evidence that the govt hasn’t spent enough to cover the need to pay taxes and the desire to save.
same thing, other way around- If the tax unemploys more people than the govt hired, it should cut the tax or hire (directly or indirectly) the rest of the unemployed.
