If you are mining in a populated system with stations then you are doing it all wrong...
The idea as far as i know is that you either explore or buy explore data on where to find really great spots, you either share it or keep it a secret while returning from deep space with a 40 tonnes of gold hoping to avoid pirates and too many questions.
Once 'others' find it then the gold rush starts, lawlessness, stations, eventually security arrive.
At some point as a player you decide when your 'nice little spot' is no longer profitable or safe enough and move on.
There should be no free handout, same as you get better trades and more money for exploring the further out you go the same applies with mining.
If this still proves to be true and you can't make money anywhere then we can say its bugged or imbalanced.
