In my experience, my worst enemies were exhaustion, the crab-in-the-bucket attitude of my peers, and an inability to build a resume and to network out to the people who wanted what I could do. Ultimately I couldn't escape poverty until I could buy enough gear to work up north. That money made it possible to pay for an education.
To help the poor, make it easy for them to climb the economic ladder. If safety makes this harder, I would prioritize job-mobility over safety.
