US debt is now bigger than the entire US economy
In 2012, debt surpassed GDP for the first time. EVER.
Ever since then, there’s been no looking back…

CBDC is a answer
To be fair some of that is debt that some Union agencies owe to other Union agencies
But a bunch of the GDP is also government spending & the unfunded liabilities are basically debt that doesn't pay interest until later
Net debt held by the public is probably 125%-130% of productive capacity
Net liabilities are probably something like 600% of productive capacity
