Even the Rome collapsed eventually ... it just took much, much longer.
"What we are looking at is America in an irreversible decline."
Yup. Has been since "oil crisis" and disconnecting the dollar from gold.
Only the poor has to pretend they have money and fiat money is always pretend money: Absolutely worthless.
Of course the actual decline has started even earlier, but the latest trick of outsourcing manufacturing to far East was the last nail in the coffin.
There's only so long you can sell stuff made in China to unemployed in the US with astronomical profits. "Lower price" is irrelevant when people can't buy even food.
Once that path ends, and it will as it's a dead end, you don't have buyers nor manufacturing capability. All the capital gained is parked in a tax haven and it won't come back from there either: Owners are happy with that.
