I fully agree that the best universities don't have the exclusivity on the best output, but the classification of what is considered "best" should be based on the average quality of the output.

Also recruiting in universities is an effort that does not scale, I did that for about 5 years and it was not possible to reach all the universities in my country, so I had to limit myself to the universities in the top 3-4 cities that I could reach. Yes, I left out some that may have some good candidates, but this is a limitation of resources and not an intentional exclusion "I don't go to X because I don't like them". In the old days companies were not putting announcements to hire in every newspaper in every small city across the country, but only in key places to maximize output per cost.
