Comparing averages, I agree. Most of India is rural poverty, with few good hospitals. Or, for that matter, few good toilets.
Comparing the places available to me - an upper middle class professional - I strongly prefer India. Spine surgery cost me 1 month of the average Indian software engineer's salary (vs easily 1 year of salary in the US), and quality was equivalent.
My doctor was as good as any in the UK (he was licensed to practice there, in fact), he just came back home for family reasons.
