Wrong.
They never printed huge amounts.
Only in response to the 2008-2009 financial crisis and the corona crisis.
We shall see if this second attempt will be successful or ends in tears.
What about quantitative easing? It was going on since 2008 to keep the US economy floating.
American budget/expenditures are beyond their current local revenue sources/GDP. They print money from thin air to run their oversized government. Unsustainable arrangement fuelled by global reliance on Dollar.
Whenever they face a deficit they run to the Congress and pass a bill that lets them borrow more money from federal reserve (create new dollars)
This system is not sustainable at all. It's like living on credit card somebody it will bit le you in the ass.
