It tricky. The value of a top MBA is much, much, higher than the tution. At most US schools, the cost of the MBA is similar to the cost of other degrees at the same college. So, the fees are linked to the value of all degrees and are limited by both affordability and the growing debate over domestic student debt. The falling supply of employable applicants for full time MBAs can't really be effected by fees, since immigration laws and work permit controls nudge international applicants towards STEM degrees, with similar annual tution, and other countries.
