I get your point - it's obviously easier to solve the problem (at least if you want to act ethically) by improving infrastructure.

But that also has the risk of trivializing the problem. Improve infrastructure is hard, especially in a compromised system.

Genocide (which I assume is the "unethical" option) is also hard, and tends to destroy infrastructure as well...

I do agree that improving governance is much, much easier said than done. And to be fair, India has had substantial progress.
