Even the working poor in the US could probably scrape together the kind of sums mentioned in the story - about $4000 inc a flight. Though I guess time off could be an issue. Still there are probably a lot of people with like $10k in the bank that could afford Indian care but not US.
Sure, I don't doubt that. But it's not a fix to the core problem. More of a segmentation of the market. I doubt a lot of the working poor use Uber with any regularity either.
