Ok, every time i change to democracy my whole empire goes down the tubes. I will have a nice city size 13 or so that has 12-13 in production and then i switch to democracy. My population is imediately angry with me, and now growing faster due to the increase in food supply. That i can live with and even expect from democracy. But all of a sudden my 12-13 production is 5-6 production and loads of waste and pollution. I have had 8 cities with over 10 production and they all dropped to below 5 production and the rest pollution, and thats without any factories. adding a recycleing center will help but i never get to the point i was when still a monarchy. I currently stay at monarchy for this reason and just make up for the loss in trade and science with caravans, since i can produce about one every turn when i build my factories. Just for fun i built a factory and the hover dam wonder, my entire city radius was polluted in three turns.
