My experience is that the entire value of an MBA is in the network of people you meet through business school.<p>I asked a friend who had a technical degree from an excellent university, and later got an MBA what useful skills he learned, and he flat out said that he only got it for signaling purposes.  As far as new ideas&#x2F;notions, it was basically absolutely nothing.<p>A quick glance at any publication on &#x27;managerial studies&#x27; will confirm the total vacuity of the field.  The average published article is a &#x27;just so&#x27; story backed up by a dramatically statistically underpowered study.  Managerial science makes social psychology look like quantum physics.
