Over production is good and nearly always produces $$$.

Greed is nearly always the desire to over consume which destroys $$$.

Subtle difference but vital.

Wanting to eat 2x is bad
Wanting to farm 2x so that you can feed someone starving is good.

Farming 2x and eating 2x is neutral/slightly good as the result is more or less same as farming 1x and eating 1x.  But if you fail and farm only 1x you still don't starve thus it is slightly good.
