Before you poo-poo my suggestions, perhaps you should do your research.
Why did Rome Fall?
There are adherents to single factors, but more people think a combination of such factors as Christianity, decadence, lead, monetary trouble, and military problems caused the Fall of Rome. Imperial incompetence and chance could be added to the list. Even the rise of Islam is proposed as the reason for Rome's fall, by some who think the Fall of Rome happened at Constantinople in A.D. 1453.
Notice 'decadence' is mentioned, 'monetary trouble', and 'military problems' and surprise,surprise, so is 'Islam'.
Sounds rather familiar to today's problems.
And whereas I don't possibly agree with this, (so don't rush to label me homophobic), it makes for interesting reading.
