It's not like I really have a choice in the matter. Either I keep it fed, and it grows in population regardless of my wishes (wishing I could force additional growth in population to emigrate elsewhere), or I let it starve, and the city stats plummet, and I go back to where we started, low population and little gold. To start the cycle all over again. IF it doesn't go rogue before I can get food to stop the starvation after the population has dropped.
This is a real concern. If it were possible to keep a city at a lower population without regularly going into starvation and degrading your infrastructure, then food would not be so much of a problem.
