Squalor always became way out of control in my RTW campaigns...to the point where I would max the public health systems and public health related temples as early as possible. In some of the later games I would camp a "purification" army in between 4-5 cities and when squalor was too high I would just let the city revolt, put the revolt down, and murder most of the population


needless to say I hope I don't have to do this in MTW2
