Or supply/demand was bugged. It makes no sense that hundreds of commanders endlessly fly T9s filled with crap back and forth to pretty much irrelevant stations and earn obscene fortunes in no time while doing so. Its a bug in the BGS, not a sensible feature. The BGS should result in temporary 'gold rushes' that you find yourself for you and some friends. If endless number of people can endlessly grind it for no discernible reason it has nothing to do with supply/demand in the first place.
In other words: trade missions need to be tied to the commodity markets.
It's wasn't even a gold rush. Passenger missions were a gold rush. This was a fraction of that. People have only been looking at trade missions recently becuase it was the last line of work that hadn't dried up, and could actually make you money, rather than just break even.
That's if it is dead however. What rank are you with the local factions OP. Stations out there work the same as anywhere else? The friendlier you are, the bigger the pay. Unless you mean no more missions, which now that is silly becuase it's a mining outpost, it should still produce some goods. If not, then we're in the land of magic farting unicorns....
