I think the key word is "build". As someone with both a Master in CS and MBA and have previously been a CEO where I was hired to run the company (not a founder), and now starting my own business, I can attest that its the engineering side of me that pushes me to be a founder and build something from the ground up. Although, I will say that some MBA schools are promoting entrepreneurship as a viable path more now than before. My alma mater (BYU) now has an Entrepreneurship major I believe.
