Reports that the USA government’s total financial commitments from the financial crisis now top US$5 trillion raise the obvious question “Can they afford it?”.
The answer isn’t obvious. Some economists, from a range of schools of economic thought, argue that the government sector (lumping the Treasury and the Federal Reserve together) has a limitless capacity to pay debt as a consequence of its status (especially since the US dollar is still the world’s reserve currency).
I don’t dispute the capacity of the government sector to issue debt. But if it is to service that debt then there are financial issues for both the government and taxpayers if the debt it takes on is huge.
