I look at some of the characteristics of when the Roman Empire fell and its "play to the masses" The excesses' in the higher classes is what a lot of history references want to point at, but some critical scholars look at citizenship and pandering to the masses.
This was how the the ROMAN catholic church started as the new state religion of the Empire. The emperor saw many of his soldiers had Christian symbols on their shields for luck (not pagan) and decided this was the "new way forward" That's why the Pantheon is the oldest church, it was the first to be converted from use paganism to Christianity.
Secondly was citizenship. To be a "Citizen of Rome" carried a lot weight in the world. Many wanted it, and it was given out sparingly. It was a social currency that kept the other 95% of the population working to maintain the strength of Rome. Most Romans were Plebians (a social order with its own records and rules), while the equestrian, patrician or senatorial. Once Rome granted citizenship to almost everyone within the empire to placate conquered peoples and keep the masses happy, citizenship lost its value, and as the outside and colonial bodies grew strong and belligerent the decline became more rapid.
Today, the Biden/Democrats/US gov't is toying with the idea of blanket amnesty for illegal aliens and with that voting rights and if its not clear right now, perhaaps granting citizenship.
I see parallels in the nature of the empires, how they grew, and they peaked, and now to watch how they fall.
