One of the less well-known economists of the Austrian School was Professor Antal Fekete who died in 2020. Fekete arguably had a much better grasp of monetary issues than many of his contemporaries. His works are still available on his website, and one in particular details why debt must necessarily grow exponentially in a fiat currency system.
Every year monetary authorities must create at least as much new money as needed to service outstanding debt, in order to keep the game of musical chairs going.
Governments have lost not only their option to reduce indebtedness but, more ominously, the option to balance their budgets. There is a new item in the budget that is never named, that is well-hidden, but that is increasing by leaps and bounds year after year: that part of government borrowing that is needed to provide cover for the increase of the monetary base.
The utterances of politicians about their resolve to eliminate the budget deficit is disingenuous – it cannot be done under the prevailing monetary regime on a net basis.
