I later worked overseas (in Guyana). I've seen many bright young people worldwide forced into doing work that crushes their spirits, because they either never had access to educational opportunities, or they struggled with rigid educational systems.
Education is one of the few ways to reduce systemic economic inequality, but it's getting harder to get a cheap, high quality education over time.
I'm building Dataquest, which to start is teaching data science online at low cost. Dataquest teaches skills in depth, so students really understand the concepts and can apply them with projects (vs most syntax focused online learning). We've had students get jobs at companies like SpaceX and Amazon.
I hope the positive impact I'm having is in some small way helping people achieve things they never believed they could.
