Actually the similarity is far worse. Rome fell because it could not control its borders. The barbarians moved in and took over.
A bit off topic.
The show “Big Dogs” (8 episodes) opens with an NYPD captain lecturing a new hire on the fall of the Roman Empire at Noricum Ripense, and then pours some whiskey in his coffee. I found it to be pretty amazing viewing. A future(?) New York where several gangs are vying for control of the drug trade. Violence, drugs, and language.
“BIG DOGS exists in an alternate reality of New York City. Businesses are shuttered, crime is rampant, black markets thrive. Drug are run via taxis and NYPD detectives use taxis for undercover teams trying to rein in the chaos.”
