I know that this is a problem, and I don't blame you.

However, one of the admissions committee members of a top-10 US university told me how they deal with this problem.

That they keep track of good universities in India, and what GPA is considered good in India. Occasionally, they take a chance with a student with an interesting resume from an unknown University, and continue selecting from there if that student does well. Repeat this process, and over time they end up with a good list of sources of good students from India; and they ignore applications from all other Indians.
