I don't think they're regurgitated talking points. I think it's an accurate comparison to the collapse of The Roman Empire. We can point to the overextension of the military as another reason for America's decline. Of course I don't have all the answers. If you have more context you'd like to add, please do.

Let’s start with economic influences, OK?
One sign of the coming fall is the fact that the United States has been devaluing its currency for over 150 years. Just as the Roman empire started, making smaller, thinner coins and assigning the same “value”.
This started with the issuance of “greenbacks” ainstruments of debt instead of hard money for a completely unnecessary Civil War. Although the United States returned to a gold standard shortly after. In 1913, the federal reserve was created signaling the beginning of the end of hard money in the issuance of debt as currency as we understand it today. When you look at a dollar bill it says it is a federal reserve “note.” a note is an instrument of debt. Not an asset. In 1930 executive order 6102 confiscated gold from the citizens of United States, pushing us further off a hard money, standard and deeper into fiat debt. The last directions to the gold standard were raised in 1971 and our money has been worthless ever cents. Inflation comes from an over supply of money. For example, the current inflation the world is experiencing now is due to the fact that the United States increased its money supply by 30% beginning in 2020. We are all working for a currency that can be printed for free at a whim of someone in a position of power.
