I used to work for a company that had about half of its employees in India, and I was curious about the cost of living there. Looking at apartments in a major city, they were not a great deal cheaper than the US. People frequently claim lower salaries in countries other than the US are balanced by cheaper prices, but my impression is that a developed-world style apartment and car are usually comparably expensive pretty much anywhere, from London to Noida. Mathematically, cheaper rice can't make up for it if you are making enough to live in an urban area.
