I have all my taxes (except tariffs) at 0% (since I'm mining so much gold), and yet the contentment in my provinces still drops every quarter "due to high taxes". This is annoying because production sites are being shut down and there seems to be nothing I can do about it. Referendums and other contentment-increasing decisions seem to have little effect. It doesn't help that average militancy is 25%.... Anyway, why does my population think taxes at 0% are too high?
>>Tangentially, the Maricopa region (Phoenix) keeps being pillaged. I have sent cavalry there with attack orders, and they've never found anything, even when I leave them there for several turns. It has colony status. I have left them there during pillage recalculation turns (with supplies so they don't cause the pillaging I'm trying to stop), and still nothing.
