I don't know if anyone is still here. But, just in case: I switched from Monarchy to Democracy. My cities a ways away from my cap were mired in corruption. For example, under Monarchy, New Brandenburg. 15 production, only 2 usable. 16 commerce, only 3 usable. After Democracy, exactly the same. It says minimal corruption under Democracy. I let it run a few turns (after returning from Anarchy) and no change. Shouldn't there be a change?
