I know the parent talked about salary but that's not the only important factor. The reason for coming back to India could be spending time with old parents(who usually don't like moving to other countries at old age), kids' future, and weather.

I completely agree that those are important factors too (sometimes much more so than salaries), but good salaries, type of work and first-world benefits are usually the reasons why people emigrate in the first place (often leaving family and good weather behind), which is why I talked about those. The more India closes the gap on these, the less incentive there is for people to move.
