Many of the same reasons that caused Rome's demise, are present today in the US.
No, they aren't.
The Roman empire fell because of *rampant* civil war, technological stagnation, and a massive migration of people's into its territory. On par with say, the whole of South American flooding into North America in vast Armies.
The Civil wars were by far the most immediate cause. With one general after another trying to make themselves emperor by the sword. In the 3rd century that had literally 50 years of nearly non-stop civil war.
A full half century.
It took a horrendous toll on their ability to govern, their infrastructure, their military and most importantly, their officers. The roman army that existed in 285 was a shadow of the force that existed in 235. So depleted where their ranks that they had to heavily conscript and incorporate foreign auxiliaries until these forces were the bulk of their own. With Roman or Roman trained officers leading the forces.
We have *nothing* like that. Nothing.
Rome faced territorial pressures from the Parthians (Persians) to the South East, the Gallic and Germanic tribes to the North, and the Goths and Huns from the North East. All while it pureed itself with civil wars from the inside.
We have no parallel for this either. As we have oceans on either side of us. There is no nation that is putting territorial pressure on us. Nor plausibly could. Our military is at its technological and practical apex. Our territorial boundaries, their furthest extent. There are no civil wars, nor have been for 150 years.
The 'parallels' are a joke.
The parallels exist and you have even identified more than what I posted.
No, they don't. The 'debasing of the currency' wasn't a major cause of the collapse of the Roman Empire. Civil wars, technological stagnation and massive invasion were.
Rome allowed massive immigration of foreigners into their nation, just at the US is doing.
Obvious and blithering nonsense. The Gallic tribes that invaded, the Germanic Tribes that invaded were not 'allowed' in. They fought their way in. Armed to the teeth. They didn't come to landscape, make food and clean hotel rooms.
You're laughably confusing invading armies with migrant workers. Your allegory is simple nonsense.
Nonsense only underlined by the fact thatRome was faced with territorial pressures from all sides. The Visigoths from the West, the Ostrogoths from the East, the Parthians from the East, the Huns, Gallic armies from the North.
None of which are 'migrant workers'. But invading armies and migrations of entire peoples.
We have no such territorial pressures. Nor do we face any existential threats. And of course, you ignore the ENTIRITY of the Roman Civil wars, despite them being the single greatest factor in the collapse of Rome. While our military is at its apex, having never been stronger than it is right now.
Just another element of similarity. Rome was in constant wars, like the US, and wars are very expensive. There are more similarities than dissimilarities.
Wars of 'conquest' largely wrapped up With Tragan at the beginning of the 2nd century. What followed was overwhelmingly defensive actions, defense of their own territories from outside threats....and most commonly by far, CIVIL WARS from within.
We have none of that. Nor are any of our wars involving our own territory. Nor do we face any conventional existential threats. Nor have we had a civil war in 150 years.
You're desperately ignoring enormous causation in the collapse of the Roman Empire. With decades of civil war never even mentioned. And just as desperately stretching to an absolutely ludicrous degree to make your 'parallels', confusing migrant workers with invading armies.
