800$ is a very big sum for a lot of my countrymen. Also it is true that a lot of Indian schools operate with very few resources, that would be required to appropriately educate all the students they serve. And this makes them noncompetitive in international university rankings. And to be frank it is not in our interest to pander to the rankings, because they encourage expenditure of a large amount of resources to train a few people who may or may not directly help the nation's economy.
I don't think rankings are as important to even individuals as access to employment opportunities. The cost of college education has to be weighed against the return on investment. If for example, the H1B restrictions are tightened to the extent that foreign students aren't able to find job opportunities, then the ranking of the university would be irrelevant in absence of decent return on investment.
I believe the same holds true for the native students seeking graduate education. If the cost of education is too high, be it monetary cost or opportunity cost, the people will not seek it.
