Hi there,
You can make something like industrial designer Gabriele Diamanti:
He had the same thinking as yours. His goal is to help poor people get benefit from cheap products. To prevent any company tried to make profit out of his Eliodomestica design, he redesigned it to become easily to be produced by any craftsman.
Since you seem confident with your I.D skills, I think you are able to reach any goal you want. Can I.D design help with crime? gangs? poverty? Yes, you don’t need permission from anyone.
The reasons I.D designers create products for the social needs and for money, because they are realistic demands. We should survive before we can help the others. So don’t blame the world too much.
Glad to read your thread 
good luck with your goal !
