OK, you're lazy. {;-)
Did your friend in the investment game get sufficient answers from the dean of my department that runs the business department? I saw one answer that said he had to have a masters to teach that particular subject and saw no more correspondence.
The only exception to that requirement for a masters is teaching Career/Technical Ed (what we used to call VocEd) such as welding, woodwork, electronics technology, and the like where a simple bachelor's in any field and X years working in the field. X is a function of subject and level.
