Based on what you've said, I think you'd find this recent book useful:

https://www.amazon.com/Prosperity-Paradox-Innovation-Nations...

It describes:

- why the way to help 'poor' countries improve economically is through innovation, not through aid

- examples of businesses that started offering things like health insurance and heart surgery at extremely low price (so low that, when you read about it, you will be surprised and doubt it's possible, even though I've primed you by telling you ahead of time).

You might find entrepreneurial ideas in there you want to pursue, or companies you want to join.
