European Business School Ranking
In my opinion, MBA is like any other product or service. It provides value for some and no or low value to others. Majority of the MBA students do not invest any money, but their fees are paid by their companies. On the other hand there are more and more people who pay on their own. For these guys it is rational to evaluate the potential ROI, right? Therefore possibly for them this ranking would be a good indicator. However as with any other investment in future there is never a guarantee for higher salary or even a positive change. It is the nature of any business activity.
