This. The main problem at Indian undergrad institutions is lack of good teachers. And that is because of poor pay. I went to a top colleges at one of the decent universities (a step below IIT / REC). I had exactly one great teacher who was passionate about his subjects. 10-15% were decent. But most of them were a joke. And my friends at other colleges under this university, too, had similar experiences.

Apart from good pay, another reason for having poor teachers is reservation / quota for teaching positions. So even if someone doesn't deserve to be teaching, one would be doing so just because of his/her caste.
