> As a side note: The Economist MBA rankings 2021 have raised eyebrows because European schools rankings increased so much: https://whichmba.economist.com/ranking/full-time-mba
Notably this list is missing most top-tier MBA schools like Harvard, Stanford, Columbia, Wharton, Northwestern, U of Chicago, MIT, UC and others.
If you want to say some of these schools are overrated, fine, but if none of them made the top 90 you've got a weird rankings methodology that isn't gonna be useful to most people.
