is there any degree or program nowadays that actually instructs a person on how to start their own small business and run/grow it? thats not really what MBAs do anymore. or is it just so easy that you can buy a book on amazon and make it happen?
This depends entirely on the program you are enrolled in, and the electives you choose to take. I have an MBA from Babson and every elective I took dealt with entrepreneurship. Some of the professors were better than others, but at least 1/4 of my total courses were taught by people who started their companies from the ground up. Real entrepreneurs that made money, cashed out, and are teaching because they want to help others; these were the people I found worth listening to.
These courses were by far the most valuable, and they absolutely focused on how to run and grow both small businesses and enterprises. I even started my first (failed) company and got independent study credit for it.
