Question normal

Are we doing a dis-service to our MD students by letting them go through an MBA during their MD-training, especially in circumstances where they don't really have an idea as to what kind of business or aspect of business they want to pursue? Isn't it better to do an MBA, or so I've heard, when you've got a clearer focus? For example, many residencies are now pairing residency training with the MBA, or folks are getting MBAs after their training is complete. Thanks!
