While the point you are making is still solid and worth pointing out, I'll note that as someone that was once a retail management stooge that these "courses" are basically just suckup programs that rarely factor into actually getting promoted and are run so rarely that 99% of management won't ever see them.

Its closer to the company paying for you to get an Associate's Degree in Business for everyone to laugh at than a "requirement" to get into management. Unless Best Buy's version is an exception of course.
