I make 280 of my 4919 weekly BCs from trade, less than 6% (I even have econ bases along the trade routes), and I make 813 BC from Tourism, and thats ~16.5%. |
On the average, I rake in 1200 to 1500 BC per week in trade alone. With 90 to 100 percent approval. Add that to my taxes and tourism (I always go Neutral), I bring in roughly 3,000 to 5,000 BC per week grand total. If I jacked my taxes up from 18 or 20 percent to 40, 50, even 60, I would have a massive income...
The thing is, I only build as many morale projects and farms as I need, the rest goes into research and military.
I think economy starbases only work when the planets the trade is coming to/going from is in their range... Not along the route itself.
