India is orders of magnitude better than most African countries. At the very least it’s safe and you can make a living. Indians actually move back to India after living in the west which doesn’t happen with Africans all that often.
e.g in Nigeria most professionals hardly earn $500. Now compare to zimbabwe - the same professional earns 2x-4x the nigerian wage. Yet Nigeria has higher gdp per capita.
so yeah gdp per capita or gdp per capita ppp - might really reflect the african dynamic.
Or to give a rather poor analogy for lack of better one, India has premium-business-class experience migrating to West, compared to other APAC, which are put through economy-saver class experience.
