First, being consistently ranked beside MIT’s, UPenn’s, and Stanford’s is not the same thing as being at MIT, UPenn, or Stanford. Second, this kind of thing is much more valuable once you're older and have some perspective (hence the MBA). Business degrees are generally about operational aspects of running a business, not the startup aspects, so if you expect them to teach you how to build a run-away success you're in for a disappointment. That doesn't mean a business degree isn't valuable (in and of itself it doesn't mean it's valuable either, but at least you should know what you're getting into).
