lumber saves me a lot more on bills than cattle can make for me so lumbers is 4th above cattle. It may be less effective for younger nations but once you break 6000 infra it is a must have. Lumber keeps growing in effectiveness. As I grow to 15000 infra I would imagine it will save me double the amount cattle makes for me. My bills are 8.58 million and most of it is infra upkeep.
My lumber saves me 1.3 million dollars in bills alone despite savings on infra purchasing. As I grow this grows faster than cattle can make for me.
Cattle makes me only 1 million dollars
