Cannot speak for other degree programs at UMich but their B-School is one of the top in the country so it **kind of** warrants the high price tag.
Ross has the advantage being in the United States for American students, but the Imperial College of London Business school Global MBA ($48,000) vs Ross' Online MBA ($112,731). I don't think it worth $112,731 for an MBA when there is no guarantee of the future employment.
