I tossed this in my head for a bit, and I think this is the best answer I've been able to come up with: I'd wish for a few randomly chosen people who I don't know to receive a wish that they must spend selfishly.
I gain literally nothing from this, and since they must spend it in a way that benefits only themselves, it doesn't contribute to a greater good.
As far as how this manipulates reality? We'll have to see what they wish; hope they're not evil!
