relative to inflation, hasn't increased much. also, fine if you are single but once you have a family with kids, you feel the pinch even if you are with one of the big ones. The biggest issue for me is the time. Do politics, become PM and then chill all you want. As a techie, you will not have much time for family. Also, as a techie you still hit the ceiling very soon. If you are happy with the job abroad, stay there. Its not as rosy in India as the media somehow shows you.

I left India 3 years back and from what I gather, salaries at reasonably good places have pretty much doubled and in few places tripled. Am not even talking about Google/Fb.

I agree, but you also have to consider the crazy inflation rate there. Not to mention cost of housing and no decent public infrastructure. You need a lot of money just to get a reasonable standard of living there.
