So, I just increased my region's tax rate from 19% to 22% and instead of "peasants complaining of high taxes"
I'm now getting this response: "Taxes are too high, hurting production and trade."
My production dropped 6% in one day in addition to a 10% morale drop.
The morale drop I can deal with, and can fix with regular courts. I was expecting it, but I wasn't expecting the production drop. Is that going to be normal? I figure I probably can't maintain these levels of taxes if it is even if I keep morale above 90%.
