Your comment is weird to read because you say it’s fine because “these things move in cycles” [created by debt, tax, and monetary policy] and the article describes why the system that generates these cycles is “encumbered” and lacking in strength.
I could imagine you may not understand the cause of economic cycles. As you say in the “real” world, you only notice the lived experience of macroeconomic policy, which is what matters from a governance perspective. That’s why politicians talk about “kitchen table” issues to keep popular sentiment but govern through a seemingly backroom set of central bank, tax and trade policies.
It’s not complicated to see that the GDP will grow proportionally to the deficit growth and shrink proportionally to deficit cuts. That extra money is borrowed from the future and injected into today, goosing GDP.
Then the debts get expensive as capital gets tight, interest rates rise and the weakest businesses go under, contracting spending and destroying money as cancelled debt, tightening capital more and consumer confidence. And them the economy shrinks again.
It’s great when the central bank is buying the drinks but the party will end when their credit card is maxed.
