How do I keep the poverty line down? It's always so high and I can't keep up with my colonist demands.
Use the buildings that export/import items (ones that do both of them, the export ramp/gun, galactic freight, space elevator, stargate(s), and spaceport). Then you export (sell) the following:
food
water
rum
toys
Those are what goes into the numbers from what I can tell (if anyone knows of any others, please add them). These also tend to max out their storage fairly quickly, so you get the added benefit of keeping workers on the job. Do this, and the poverty line goes down. You will have to sell *a lot* of them though. As in hundreds of thousands of units. But it works.
