Do Republics Collapse into Plutocracy (video)

I read the post I wrote about the political transformation of Republics into the tyranny of the rich (plutocracy) that may result in an emperor (Caesar).  Either the rich may concentrate wealth and phase out Congress perhaps making the President an imperial stooge, or the public may demand a Caesar to counteract rich oligarchic Republicans. A depraved plebian set (democrats) may enjoy soma (dope) , bread, circuses and so worth with occasional military adventures in the empire. Maybe something like that happened in ancient Rome and will occur in the U.S.A.
