Yes, I know, but, well, I often don't really care about, the game flows even with that and I still win with a large and strong empire within my hands, while always typing a cheat in order to reduce my treasury (my introits every turn are very large, actually I reached the 4.000.000 pieces of gold) would be terribly boring (and I also don't want to select every single city and change taxes so that I won't get too much income but still enough for paying upkeep and wages).
