Industry: Industry takes raw materials and turns them into Consumer Goods which can be sold on the market or eaten by your population. Population has a certain amount of Consumer Goods demand (dependent on race) and you can feed these goods to them for $5 each. If you make a surplus, you can sell the goods on the market for $4 each. The best race for making goods is the A.Miners. The best planet is a U.Large, or anything with lots of land on it.
