Many peaople say: "manage your cities better, then you will have no problems with squalor and revolting".
That is true for roman factions, wich have many, many helpful buildings.
But other civilized factions have it a whole lot hareder.
Carthages cities can grow as big as romans, but cartage lacks many health buildings and hasn`t the option for races and games like romans have.
Sure, you can build you secret police, but that doesn`t by far help as much as having an aquaduct and monthly races would.
Disliking genocide, I can only helplessy watch as even cities without any culture penalty revolt.
