Tax doesn’t finance spending. That national debt is owed to no one. Money is created out of thin air, my friend, and always has been since fiat money was introduced. When the government spends, they just adjust the number on their account; they’ve come right out and admitted this.
“We can’t afford that” is a lie. They can afford absolutely anything, because they own the money, and they own the debt in that money - it’s a constructed fiction.
Printing large amounts of money out of thin air is a great way to turn a valuable currency into worthless Monopoly® money via inflation. That is basic economics. There are lots of examples for that in history.
Inflation is not a guarantee, that depends on the actual economy. Japan is massively in deficit and yet is seeing deflation.
Beeing deficit doesn’t have to mean that they print money, they can be deficit by taking higher and higher loans. Which comes with it’s own problems.
