Literacy rates in India look to be ~80% and climbing about 1% per year. Obviously it'll reach an asymptote, but it's looking like India already surpasses the US in this regard. Of course, given the large population, more Indians are illiterate than there are people in almost every nation. Nonetheless, wouldn't this solution be quite niche?

I thought you were joking about India surpassing the US in literacy rates, and then I looked it up. It's 75 - 85% depending on how you count. What?! How is this number not 99.9%? Developed countries are at 100% or minus rounding error. Even Canada is at 99%, and that's next door. What is going on in the US?
I think you got it right there. Be wary of cross-nation statistics without context.
