This is also racists. How many Indian engineers are there vs rest of the world? What kind of work is getting outsourced?

Let's take your words only.

Manual processes which are bug-prone and faulty are getting outsourced. They handle it with their best knowledge. Some processes/data knowledge is never transferred and some are kept hidden and assumed from outsourced teams but they have different culture and exposure so their understanding of things might be different. Its expectation mismatch not team issues.

American software giants are run by Indians only. So, if they are bug-prone & faulty then how could they reach there. It just that when person study with you or live with you then they have same set of culture & exposure like you have. So, they can manage things effectively.
