Same here, i have NO money and i am in the Yellow nearly 3/4 of the time, , then you add in subdue animals you want to keep and POOF you are in the RED, this just does not SEEM right IMO. Thats why i though maybe 1 more city might work, but then it only adds to the problem of

But at lest if we increase it by only 1 city it might help out if you dont keep any animals at all??
EDIT: Actually i just also noticed, if you want to be a Warmonger, there is NO WAY you can, you'd have to RAZE each and every city and be left with hardly nothing also??
(Attached) there is so many resources avail, i need that city, but CANT because it would put me in the RED for financial difficulty, now i dont know if it is strictly civics, i kind of doubt it, i am sure its a combination of LH Traits and Civics, but its just not very good gameplay when its like this

Besides being bad for other gamers also
(sidenote) i do have alot of animals in a city, but it didnt matter in the PreH Era, i butchered all of them and was still in the Yellow.(pic 2)
