Hmm, so this is coming from a person who only had to pay 10k USD for their MBA. The reality is that most of us face an MBA option of many times that in costs.
Should a person seek to get an MBA from a more highly-ranked school than where that person completed undergraduate studies? A lot my undergrad classmates (top-25 university) are getting MBAs from a less-well rated private university.
It depends what you want to get out of it. Do you just want the knowledge or do you want the prestige as well?
I will say this, if you don't have an MBA from a top 15 school, your employment options are drastically reduced. That being said, if you're doing your own start-up and you want a well-rounded business education, does it matter that much?
As I mentionned in my post, I realize that I was really lucky thanks to Quebec government subsidies and that the financial ramifications are significant. However, you can often have your employer subsidize part(or all) of your tuition.
Ultimately, the value of an MBA is significant but the decision to undertake one is very personal. You have to weigh your own value for education with the cost you'll incur.
