Working a model liberated me from ever having to hold a day job. I transitioned from doing that to working full-time as an artist. If you're 19 and living cheap, being an artist model can sustain you. I dropped out of college at 21 and my illustration hadn't yet taken off. It is more than working in a store. It is a hard way to make a living but you earn more than in a similarly unskilled job.
But the improvements will happen faster and last longer if we can channel market forces, including innovation that's tailored to the needs of the poorest, to complement what governments and nonprofits do. We need a system that draws in innovators and businesses in a far better way than we do today.
