That's just silly, absurd. More gold, = better irrigation to prevent drought, better silos to prevent rot, better tools to plow or to harvest, etc, etc. If you invest in agriculture in real life, you definitely WILL increase production. We aren't talking about wild blueberry picking here (and even then).
No, you are being silly and absurd. Read what the others have written, and you will understand what I mean in the correct light. 100% is the
maximum attainable production, this is the last time I will say this.
