@talk72000,
Sorry but there was many reasons why the Roman Empire fell and it did not do so for a thousand years in the West and two thousands years in the East and during all that time the conditions you claimed that cause it fall did in fact exist.
Second, the poor did not in fact vote for the Emperor and the senate became a powerless joke during that long period of time.
The great imbalance of wealth exists in all pre-industrial emperors.
