I'm doing quite tangible stuff myself as well. On the one hand, I'm helping people preserving their pension funds by detecting risky situations early. These people don't want highly speculative markets or high profits, they don't want their savings protected from the money printing machine among other things. I'm also helping decide producers what should they be doing next, to meet demand and so people don't suffer shortages. I don't work for a bucket shop or a commodity hoarding fund. I help supply meet demand and more people have their needs met and better met than otherwise thanks to people like me. There would be a lot more poverty in the world without this industry. In fact, there was a lot more poverty in the world as a direct result of the lack of this level of commerce in the past. It's not our duty to stop the poorest regions of the world from over-breeding, though, which is the main reason for poverty nowadays (including pockets of poverty in wealthy nations).
