Reasons why the Roman empire fell

Economic troubles and overreliance on slave labor - massive inflation cuz by over reliance on slave labor which isn't much different then the minimum wage Jobs of today.

Government corruption and political instability hmm sounds familiar

Christianity and the loss of traditional values forced religion hmm

Overexpansion and military overspending - naww couldn't be anything

Weakening of the Roman legions - basely reliance on mercenarys that are the same as today's PMCs which we are using more and more for denyably

The rise of the Eastern Empire - the empire spit into 2 empires the only part of this list that hasn't happened yet although both sides are on about it as of late

The final straw Invasions by Barbarian tribes don't look like we are going to need outside influence at this rate

History is Always going to repeat itself since people tend to forgot it congratulations America your not even going to get close to the most power civilization in history.
