The economy is NOT a closed system.
MV = PQ
Money x Number of transactions = Price x Production
The fallacy you re-iterated depends on Q being fixed. Which it clearly is not.
Have you heard of the Witcher Conjecture?
I have not heard of the Witcher conjecture - nor it seems has Google in an economic sense - can you enlighten me.
The proposition that production is not fixed is absolutely correct - in the longer term technological change, education and training has (and probably will) continue.
However the current problem besetting the UK is that productivity is relatively low compared to other developed economies, and growing very slowly (if at all).
Increasing money supply - whether printed by the BoE or by transfer from the mega wealthy - will only increase the volume of goods available if imported. Even wholly automated production requires scarce resources - labour (install, maintain, run machines), energy, packaging, transport etc.
I subscribe to the very simplistic view that national finances are not dissimilar to the personal - albeit with more zeros, different timescales and terminology. Spend more than you earn/produce requires borrowing on which interest is payable and ultimately needs to be repaid.
Do this for too long and (a) the interest rates charged by lenders will increase, (b) lenders become increasingly nervous - credit rating suffers, (c) finally when the house is mortgaged to the hilt, credit cards maxed out etc you go bankrupt.
Pffft.
The accounting of the currency issuer has no relation to the accounting of the currency user.
Do not confuse the umpire with the players.
All Fiat currencies are unencumbered, irredeemable tokens.
Go to the Fed and them what you can swap a dollar for. They'll tell you, another dollar.
Go to the umpire and ask what you can swap a point for.
Same thing because they're issued the same way, ex novo... from nothing.
Fiat currencies are
points systems but they look like money to you and me because we're currency
users, not
issuers.
The umpire has at all times zero points but the unlimited ability to issue new points.
How was WWII financed? Every significant economy was at war.
Where did they get all the money to finance it?
The Martians?
They all just created as much currency as they needed and they could because currency,
for the issuer, is just points.
Can the issuer issue too many points? Of course! Argentina, Hungary, Zimbabwe... all concrete examples.
Can the issuer issue too few points? Of course! That's what we call
Austerity.
Does it make any sense to issue too few points? Not really. You should run your economy at maximum output at all times.
Do Fiat currency issuers borrow money? No. The accounting mechanics for such a thing do not exist.
Does the umpire borrow points from the players? And if he did, where would they go?
You can
deposit money at the Central Bank. You can swap £s for a certificate of deposit (a
bond) but that's not the government borrowing.
Think of it as a security deposit box that pays interest... nice.
There is no path from the BOE selling bonds to the Consolidated Fund.
When you buy a bond, the BOE debits your bank's reserve account and credit your bank's securities account.
Like moving money from a checking account (reserves) to a deposit account (treasuries).
All the BOE is doing is holding your money and paying you interest.
Its like the coat check girl. You hand in your coat, you get a ticket, you redeem the ticket, you get your coat back.
The government does not need to make you a new coat. It
already has your coat.
When Fiat currency governments want to spend they just instruct the Exchequer to instruct the BOE to mark up the reserve account of the bank of the payee.
Boom!
All done.
