Most of those people are making several multiples the average Indian's lifetime earnings. Should those call center folks pay for the Indians' healthcare?
That's a cop-out. Just as the CEOs could transfer their higher wealth to average Americans, average Americans could transfer their higher wealth to Indians without changing or giving input on their healthcare system.
(which is absolutely not universal in any OECD-country sense)
It's also not an American's business to come in and tell India how to run its healthcare system.
