There a over a billion people in India, and tech is where the young have been going for a while. In any large population you willhave good and bad people. In the US the bad move to something else, but in India there isn't a something else better than working for a place that will hire you cheap to produce bad code.

There are a lot of bad engineers in India, but if you can weed through them and are willing to pay there are a lot of great ones too.
