Nice, now see if you can do it for happiness. (I actually don't know if that's even feasible, as I am unclear as to how exactly the happiness mechanic works.)
It's imposible since you get +50 people per day as long as hapiness is up
to counter it you'll either have to decrease the people, but that'll cut the happiness as well
or you'll have to get atleast more then 50 happiness per day to eventually catch up to people but that would cost money
balancing all three could probably only be possible in the early game when the difference isn't this wide.
