Can you tell me what fiat currency is?
Can you tell me what fractional reserve banking is?
Since we are talking about the United States can you tell me who owns the federal reserves?
Fiat money is based on debt the federal reserve who isn’t owned by the government prints money backed by no intrinsic value and loans it to the government on interest that’s why the debt keeps growing say for example the federal reserve prints just 1 dollar and there’s no more money in circulation except that one dollar and they loan it to the government but charge one dollar interest on that loan even if the government pays the one dollar back there’s no more money in circulation to pay the dollar they owe on interest hence they need to borrow another dollar in order to pay that debt which means more debt.
How this relates to the US or any other major economy being able to repay its debt.
