I didn't say that. Listen, if you want me to describe to you how biased these rankings are in favor of Western institutions, I'd be glad to do so. For example, a common metric is number of publications, for which the accepted journals are almost entirely Western (or US-based). And then you have scores that are based partially on (perceived) reputation, for which American schools will always come first. For the QS World University Rankings, this accounts for 40% of their final score.
